Version history of DVD-Rebuilder v0.98.1

Changes from DVD-Rebuilder v0.98 to DVD-Rebuilder v0.98.1

• Added code to retry certain open statements when O/S calls return before the operation is truly completed. This should correct the occasional "Could not open ... file" errors that seems happen when Kaspersky antivirus in in use on the host system
• Updated the CCE Path detection code to verify the collected path names and look for variations
• Corrected a bug in which a certain sequence of starting, stopping, and resuming the ENCODE phase could skip one or more segments and result in "Error in UpdateIFO" due to missing M2V file(s)
• Corrected a bug in which the path for the HELP file was not correctly specified
• Added code to automatically recognize, adjust, and correct for certain types of corrupt streams
• Corrected a ReJig sizing error
• Corrected a bug in which some INF floating point entries could be read incorrectly under some numbering systems
• Corrected an issue in which settings saved before a batch process may not be restored correctly at batch end
• Improved sizing algorithm so that it can properly account for some oddly formatted discs
• Fixed a rare bug related to loading of Project files
• Updated the installer to include HC Encoder v0.19
• Other minor bug and cosmetic changes

• Added a new "Write to Blank Disc (with ImgBurn)" option under the "Mode" menu. When selected this option will, at then end of DVD file creation, automatically burn to disc using the newest version of ImgBurn. Note -- the option is only enabled if you have ImgBurn v2.0.0.0 or greater installed on your computer. ImgBurn is highly recommended and can be downloaded at www.imgburn.com.
• Corrected an error in which "garbage" data following null or padding sectors could result in unpredictable timing and/or desynchronization.
• Added code to prevent a very rare cell transition timing anomaly that can occur when the source contains an irregularity.
• Added code to reduce the likelihood of "Error #0006" on streams that contain embedded MPEG garbage. Also, as investigation showed that these only happen in "orphaned" MPEG sections (following "null sectors" created by a decrypter) that are never actually decoded, the error has been removed and replaced by a warning in the STATUS window/log.
• Removed the "Special Error Processing" option. It no longer serves a purpose.
• Improved procedures for handling sequence_end_code and still frame processing. Fixed a bug in which an end code might be incorrectly inserted under certain rare circumstances.
• Corrected an error in which the INF first_sector and last_sector may (rarely on an oddly formatted source) be off by one sector.
• Fixed "Runtime Error 6" that can occur during rebuild when dealing with very small M2V files under specific conditions. - Added routines to recognize and ignore extraneous files in the source directory -- including unreferenced VTSs that serve no purpose except to occupy space.
• Added a "hidden" setting, "DISABLE_UNREFERENCED_REMOVAL". This allows you to keep unreferenced cells and VTSs if for some reason it becomes necessary. By default DVD-RB removes any video/audio that, based upon the IFOs, is not actually used on the DVD.
• Fixed an error that could cause certain types of still pictures to not display.
• Added code for checking and adjusting for Pan & Scan mode. This should correct the problem on certain players where BOV video appears horizontally compressed and button placement appears off.
• Improved the layer_break recognition routines to better recognize and properly handle seamless branching titles.
• Improved the layer_break recognition routines to more judiciously decide whether to change cell settings in the IFO.
• Updated the installer to include QuEnc v0.71, HC Encoder v0.18, and ECLPRO v1.00 (RC1).
• Other minor and cosmetic changes.

• Fixed an error that, under certain circumstances, might cause video ticks or stutter at chapter or segment break points.
• Fixed a sizing issue in which unreferenced audio streams that exist in the original VOB files were included in the output -- but weren't properly accounted for in the size calculation.
• Corrected an error that could result in "Error 0006, Framecount differences..." when working with the null output of some ripping programs.
• Corrected an error in which an erroneous input stream might cause DVD-RB to "hang" during PREPARE phase looking for a nonexistent extension start code.
• Corrected an issue in which certain odd original anomalies might cause timing issues.
• Updated the Installer to use a newer version of HC Encoder (v0.17). This file is also included in the "Update Only" zip file.
• Updated installer to use EclPro v0.52. Includes better compatibility and support for Express versions.
• Updated the installation package to install ReJig v0.5f. This version includes several updates that give quality improvements that were implemented by DragonGodz.
• Fixed a sizing issue in which unreferenced audio streams that exist in the original VOB files were included in the output -- but weren't properly accounted for in the size calculation.
• Modified the ReJig calling procedure so that DVD-RB uses less processor time during calls. This should speed up ReJig.
• Corrected a problem in which the calculated bitrate may exceed the original and as a result make the stream incompatible with the audio on some sources. This would have shown itself as "stutter" during playback.
• Added coding for handling "garbage" sectors that were found to have caused problems during the PREPARE phase on at least one disc. Thanks to SpazzHH for finding a disc in which it was repeatable.
• Corrected a Button Over Video (BOV) issue. In some very active streams BOV may not have been reproduced properly.
• Corrected an error in the REBUILD module that could misinterpret certain input streams and as a result, throw a "ERROR 006: DVD-RB...framecount differences" error.
• Fixed a problem in which an extremely unlikely set of circumstances might cause audio to move out of sync over the course of a segment.

• Modified code to perform more aggressive detection and removal of layer breaks.
• Added some updates that will make DVD-RB work more reliably with the output of DVDFab Decrypter.
• Improved calling procedure so DVD-RB does not use as much CPU time (leaving more for the encoder).
• Corrected maximum bitrate allocation on NTSC interlaced sources in order to assure adherence to specifications.
• Corrected an error in which source filenames that are a mixture of uppercase/lowercase letters might cause "Error 0003, buffer overflow".
• Updated OPV code to more accurately hit the specified target size on NTSC non-telecined sources.
• Added measures to more accurately measure bitrates in the source stream and then distributes it accordingly in the backup.

• Modified some status routines to ensure compatibility of the INI and INF files between Freeware version and the Professional Edition.
• Fixed an error that could cause ""DVD Rebuilder experienced a buffer overflow. Error #0004.." on some sources.
• Corrected "Runtime Error 75" that could happen at start of rebuild.
• Modified the OPV encoding prediction algorithm so that it will take fewer passes on each VTS.
• Fixed an error that could cause SCR value to "drift" higher over time under some unique circumstances and cause timing irregularities and stutter.

• Now released as a fully installable unit utilizing the Installer created by Rockas.
• Fixed an error that could cause an "Runtime Error 9" upon program start or when loading a Project file when the source path is no longer present.
• Added code to disable path buttons when running any of the three phases. Previously changing any of the Source, Working, or Output paths (either purposefully or accidentally) during execution could cause various errors (including Runtime 54).
• Adjusted the average bitrate for encodes to ensure that the minimum and average bitrates were never the same.
• Added a confirmation note when audio or subpicture defaults are saved from the SETUP screen. Also removed the old screen flags that were incompatible with skins.
• Fixed an error in which ReJig could receive values greater than 100% for its reduction level.
• Fixed an error that could result in "Runtime Error 52" on certain sources when using either ReJig or "No Compression" settings.
• Fixed an error in which exiting via the Windows "X" while rebuilding is in occuring could have anomalous results -- including program lockout.
• Corrected an error in which "Steal Space from Extras" was sometimes not being disabled when loaded during batch processing.
• Added selection on the MODE menu for HC Encoder. It still works as before (using the QuEnc interface) but can now be more easily selected. You no longer need to set a path as it is must be in the directory created by the installer. Also added HC "Options" menu.
• Fixed the "Make a Donation" and "Rebuilder Web Link" menu options so they will work with Windows 2000.
• Reorganized the QuEnc "Options" menu so it it easier to understand.
• Reorganized the "Steal Space from Extras" menu so it is less confusing.

• Reorganized the "Steal Space from Extras" menu so it is less confusing

• Found and corrected a long-time vexing error that could cause "Buffer Overflow...0003" and "Buffer Overflow...0004". This is very likely the root of some of the "preprocessing" errors that have been reported -- and was accentuated in DVD-RBs "Movie and Menus Only" mode. This one was truly difficult to pin down. My thanks to Carpo, t3rror, and Numer0bis for helping to nail this elusive error.
• Fixed an error in which the TMAP tables were not being updated correctly for Interleaved and/or Angled sources. This may have caused errors in random access into those sections.
• Corrected a source of possible "Runtime Error 9" that could happen when IFO and VOBs aren''t in agreement about ILVU. This conflict may happen during PREPARE when certain types of preprocessing have been done).
• Changed output directory format. Now in the designated output directory a subdirectory is created called "DVDFILES". The AUDIO_TS and VIDEO_TS folders are created under that name. This is meant to help avoid confusion and assist in future enhancements by consolidating all files that should be written to the DVD within a single directory.
• Modified the selection routine for "Source" so that now if a directory is selected that contains a "VIDEO_TS" subdirectory, that directory is automatically tried before returning a "does not contain" error message. This seems to have caused some confusion to some users.

• Corrected "Runtime Error 6" during REBUILD on sources that have very large TMAP tables in the IFO file.
• Added code to inhibit the "...is already small enough to fit " warning when using the "No Compression" mode.
• Made a change to OPV prediction routines that will significantly improve output sizing on certain types of movies.
• Removed the restriction that limited output size to 100 percent of the original. There are rare occasions in which additional processing (e.g. frame resizing/filtering) may need additional bandwidth that is made available through extra reduction or movie-only modes. Generally, though, it is best to use "No Compression" mode on sources that would hit 100 percent or greater.
• Added code to include a "(DC)" to the description of audio and/or subtitle streams if they are flagged as director''s comments. Also added a "(F)" to subtitles that are forced.
• Corrected an error in which very rarely, under a specific set of circumstances, a 4:3 source (that has some portion of its stream flagged as 16:9) could incorrectly change the aspect ratio to 16:9 in the IFO file.
• Changed the default background color to one that is more standard. The background color only applies to skins that have no graphic that fills the background (like "Windows Standard").
• Corrected an error in which retail versions of CCE 2.67 before v2.67.0.27 would set the wrong value for "video_type" in the ECL and perform OPV rather than multipass encoding.

• [note: versions 0.87 and 0.88 were skipped and not released at all]
• Modified code so that proper structure will be created whether or not DVD Decrypter''s "Remove Structure Protection" is selected. Because DVD-RB made corrections itself, in previous versions using a source for which Decrypter had also removed structure protection would in effect reverse itself and cause long blanks at title start.
• Adjusted subpicture stream id collection so it will work properly with a multiple PGC source.
• Corrected an error in which "Reduce by 50 percent" was not being read properly from .RBD files so it was not being set properly in batch encodes. (Changed in Pro v0.89 and unreleased Freeware)
• Modified the project save routine so that now subpicture selections are also saved in the RBD file.
• Corrected a problem in which attempting to call an encoder with an incorrect path could cause "Runtime Error 52" and cause Rebuilder to abort.
• Modified audio and subpicture handling so that unreferenced streams (streams listed in the IFO attributes tables that are never used in a PGC) are labeled as such and defaulted to off.
• Fix a bug in which selecting CCE Mode on the menu was incorrectly resetting the CCE path to the one selected for "CCE SP" regardless of the version truly selected.

• Added a fix that significantly increased the point at which the "Buffer Overflow 0003" or the "Buffer Overflow 0004" is reached. While this error is normally a result of a corrupted source, I have found at least one example in which the buffer overflowed on a legitimate source. This will correct that.
• Again changed the method of encoding for very small segments. Some reports of CCE CRC errors make it necessary to create a "workaround". Now all segments of less than 60 frames are encoded using one pass VBR in CCE SP versions. Single frames encoded with CCE Basic are done in CBR. The Pro version still retains STILLS intact.
• Changed the setting for ProCoder output so the .ECL file (using ECLPro) has "seq_endcode=1" for all encodes. Since DVD-RB now removes endcodes automatically this save time by not requiring ProCoder to do so. Thanks to Robot1.
• Modified the way DVD-RB calls web pages so it uses the default browser (it was making a call to "Explorer" before -- which always called Internet Explorer. Thanks again to Robot1.
• Added a "Contents" option to the Help Menu. This will open the default file DVD-RBHELP.CHM in the DVD-RB home direcotry if it exists.
• Corrected an error in which "Reduce by 50 percent" was not being read properly from .RBD files so it was not being set properly in batch encodes. (Freeware only)

• Fixed "Runtime Error 9" error when attempting to run in one-click mode with an invalid directory.
• Added code to reduce the likelihood of false positive detection and abort in the "missing frames" check routine of the rebuild.
• Located and corrected a source of Runtime Error ''9'' during rebuild that would have happened on exceptionally long source M2V GOPs.
• Added code to reset the vbr maximum bitrate to the maximum DVD compliant rate if creation of a a .M2V file is not successful after 2 attempts.
• Tweaked the OPV prediction algorithm to try and reduce the number of passes required to hit the target value.
• Added code to properly identify and output an error message when the encoder path is invalid, this corrects the non-descript "Error 53".
• Corrected an error in which the quality_prec parameter was being incorrectly converted to a 0-100 scale. Also improved the accuracy of the conversion and removed extraneous decimal values.
• Changed "missing frames" check so that it only reports "possible" missing frames, but does not stop the process.

• Fixed "Runtime Error 9" error when attempting to run in one-click mode with an invalid directory.
• Added code to reduce the likelihood of false positive detection and abort in the "missing frames" check routine of the rebuild.
• Located and corrected a source of Runtime Error ''9'' during rebuild that would have happened on exceptionally long source M2V GOPs.
• Added code to reset the vbr maximum bitrate to the maximum DVD compliant rate if creation of a a .M2V file is not successful after 2 attempts.
• Tweaked the OPV prediction algorithm to try and reduce the number of passes required to hit the target value.
• Added code to properly identify and output an error message when the encoder path is invalid, this corrects the non-descript "Error 53".
• Corrected an error in which the quality_prec parameter was being incorrectly converted to a 0-100 scale. Also improved the accuracy of the conversion and removed extraneous decimal values.
• Changed "missing frames" check so that it only reports "possible" missing frames, but does not stop the process.

• Implemented new procedures to prevent unreported overflow errors that are occurring in CCE version 2.70 (both SP and Basic) from causing undersized builds (with frames missing). Tweaked several parameters that make the overflow less likely to happen, and also inplemented a segment frame count verification in the REBUILD phase to flag it should it somehow again happen.
• Added code that does a checksum verification of the source directory which is now used in the ENCODE and REBUILD phases. There have been several reported errors that were caused by attempting to encode or rebuild against a different source than was mounted at the time of PREPARE.
• Made several changes related to how DVD-RB handles sources that have a width of 704 pixels. While these are very uncommon, they are within the DVD standard. There should be no more problems with reencoding these sources.
• Changed the mechanism for setting maximum bitrate for VBR encodes. The previous method was overly aggressive and could cause rates that are too low that might force buffer overflows in CCE.

• Implemented new procedures to prevent unreported overflow errors that are occurring in CCE version 2.70 (both SP and Basic) from causing undersized builds (with frames missing). Tweaked several parameters that make the overflow less likely to happen, and also inplemented a segment frame count verification in the REBUILD phase to flag it should it somehow again happen.

• Added code to reduce the likelihood of false positive detection and abort in the "missing frames" check routine of the rebuild.
• Fixed an error in which some of the options that are not available in "No Compresssion" or "ReJig" modes were not properly enabling/deenabling as modes were selected.
• Correct a problem in which VTSs that were 100% ILVU content were not included in the output directory.
• Revamped the processes associated with removal of subpictures. In previous versions it was sometimes possible for subs to be kept that weren't selected and (rarely) for the wrong subs to be removed when running in three-click mode.
• Changed the default minimum bitrate (MIN_BITRATE) to 500Kbs. It was previously set to 100. This should negate the possibility of getting CCE "MPVA VBF ovg frame #" errors and DVD-RB's resulting "ERROR: Encoder failed to create .M2V. Aborted."

• IMPORTANT FIX. Implemented new procedures to prevent unreported overflow errors that are occurring in CCE version 2.70 (both SP and Basic) from causing undersized builds (with frames missing). Tweaked several parameters that make the overflow less likely to happen, and also inplemented a segment frame count verification in the REBUILD phase to flag it should it somehow again happen.

• Added code that will automatically update your Skins if they are out of date. This is needed to ensure layout changes or possible new fields are also updated.
• Changed the displayed text of the error message in an UpdateIFO routine so it spells out any missing cells that it has found during REBUILD. Formerly known as the notorious "Contact developer" message.
• Fixed the "Runtime Error 52" that occured with the working path is invalid. A proper error message now appears and gracefully exits the PREPARE.
• Added the "adjust_q_matrix=0" parameter to ECL files to prevent CCE from using adaptive quantizer matrices as there could be incompatibilities on some DVD players.
• Corrected an error in which an exceptionally large segment (e.g. Cape Fear bonus disc) could cause DVD-RB to not integrate file into the output, causing an extreme undersize in the VIDEO_TS folder.
• Changed the button for starting batch encodes from "Ok" to "Start" -- the OK button was confusing...
• Modified the CCE Advanced settings dialog so the number of passes can't be changed when CCE Basic is selected, (CCE Basic does no more than 2 passes). This seems to have caused confusion for some who weren't aware of CCE Basic's two pass limit.
• Removed "Dynamically Assign Cell Bitrates" as a menu option. Cell bitrates are always dynamically assigned now. Not doing so detracts from output quality.
• Changed the actions taken for segments of less than 60 frames. Instead of setting to CBR, VBR is used but with a minimum bitrate. This more accurately correct the reason for adding this fix originally.
• Changed INF file slightly. Added two new values to each segment section.
• Fixed a "Runtime Error 75" error that can occur when files in the working directory cannot be cleared.
• Corrected settings that may not be set properly during a project load (e.g. during batch encoding)
• Fixed a memory leak that became especially noticable in OPV analysis using v0.81. The symptom of this problem would be an increase in DVD-RB's memory usage over time as jobs are run, and eventually cause memory swapping and slowdown after a few jobs in batch mode. Note: The leak was not persistent -- meaning it was corrected each time DVD-RB would exit and restart.
• Added code to removed sequence end codes that are added as a default on some encoders. The end code at the end of a segment can cause problems on some players.

• Added code to do a check for existing .M2V file after a segment encode is completed, and to reencode the segment if it does not (up to 3 tries). There have been reports of missing .M2V files causing errors during rebuild. Most often this is caused by an errant keystroke stopping the encode accidentally -- but it appears that sometimes an encoder can abnormally exit leaving DVD-RB without an M2V to process. This code should reduce that likelihood.
• Fixed an error in QuEnc encodes in which the maximum bitrate was always set to 9000Kbs. While this would most often have little impact there could be instances in which this could raise the total bitrate to a level that is greater than the DVD specification.
• Corrected an error where under rare circumstances the calculated average and maximum bitrates could be set to the same value. This can cause some encoders to fail or freeze.
• Added a "-maxbitrate" parameter to the QuEnc command line for segments less than 60 frames in order to ensure HC can work in the freeware version. These had been done at CBR due to problems seen in both QuEnc and CCE with very small segments -- it is needed because HC does VBR encoding only.
• Made changes to the segment encoding code to better assure all segments are encoded properly.
• Added an output line that displays how long the entire job has taken in "One-Click" mode.

• Corrected the SRI table computation algorithm to make FF/RWD offsets more closely compliant with the DVD standards.
• Fixed an error that could cause the V_F/BWD_Exist2 flag of the SRI tables to be sometime set/reset incorrectly.
• Corrected the QLB matrix switch so it works again with the QuEnc encoder (FREEWARE ONLY)
• Added the "Create New Folder" option to the "Browse for Folder" dialog when browsing for WORKING or OUTPUT folders so people won't have to go in and out of the program when they need to create a new one. Thanks to Rockas and Ryan for pointing out the flag I'd missed.
• Corrected ConvertToYV12() statement in AVS files so it is sensitive to interlaced sources. Also forced the insertion of ConvertToYUY2() when CCE is selected regardless of whether the AVSOptions selection. This was causing some problems for folks who mistakenly unchecked it.
• Added code to prevent "impossible" Q values (as a result of extreme compression -- e.g. in Half/Half encoding where 50% reduction is also applied). This should prevent getting a "Runtime error 6" when the Q value gets too large.

• improves OPV prediction for CCE
• can set a maximum number of B-frames for QuEnc
• detects different QuEnc versions
• has some corrections in the still frame detection algorithm
• fixes a bug which caused that the encoder window wouldn't be closed when you aborted the encoding process.

• Made a couple of (slight) adjustments to the OPV prediction code to try and make sizing more accurate.
• Corrected an error in which the subtitles listbox was not being disabled properly during execution. This could lead to changes during execution that might cause anomalous behaviour.
• Added code so the values selected for VTSs under "Disable Interlaced", "Resize to Half D1", and "Convert LB 4:3 to 16:9" (all under the "OPTIONS/AVS OPTIONS/ADVANCED (EXPERT) OPTIONS" are saved when set so they can be active during batch encoding. In order to protect against accidentally setting and forgetting them (causing unexpected results) , they will ONLY be activated when loading as a project("FILE/OPEN PROJECT") which includes loads in batch mode.
• Fixed an error in which switching skins while encoding in batch mode might make the Batch listbox unavailable.
• Found and fixed an error that could cause "Runtime error '5'" during the rebuild phase.
• Corrected an error in which the cell elapsed time was not being correctly entered in NAVPACKS. It was resetting back to zero for each segment (as opposed to each cell). This was reported to cause playback problems on some players. Hats off to gm901 for some outstanding beta testing and trouble reporting.
• Corrected an error in which the bitrates reported in the status window were incorrect when sources were PREPAREed with "Dynamically Assign Cell Bitrates" turned off.
• Added code to prevent the Q prediction routine from ever returning a value less than 1. Also fixed an error that could cause output from OPV to be oversized under some circumstances.
• Corrected the opv_brate_max value so the that it is contrained by the sum of the audio tracks during Q prediction (as is true in the actual encoding). This could theoretically improve prediction accuracy.
• Inserted code to recognize QuEnc v0.54 and not use the "-mpeg2mux" command line option (it causes a command line error).
• Corrected an error associated with the -cmatrix or -qlb switches in QuEnc. The -cmatrix was not getting inserted on any versions other than v0.54.
• Renamed the button for one-click mode from "Transcode" to "Backup DVD" -- the term "Transcode" was a source of confusion for some.
• Fixed an error in which the VOBU_SRI tables in NAVPACKS could contain incorrect entries in cells containing multiple segments. This could result in problems with rewind and fast forward.
• Corrected an error in which the working path selection button remained disabled after aborting a batch job.
• Added code to help prevent VBR errors caused by very small segments w/low bitrates being sent to QuEnc. Now all segments shorter than 60 frames are encoded with CBR (i.e. CCE). Also added -vbr to the command line as no doing so may have contributed to reported sizing problems.
• Widened the "ENCODE" button in the "Rockas Original" skin. It was cutting off part of the "Stop/Pause" text when encoding. You must select "Rewrite Defaults" from the "Skins" menu for this change to take effect.

• Cool new interface. Again designed by Rockas and it takes better advantage of the available space and all functions are logically positioned. Make sure you select "Rewrite Defaults" from the "Skins" menu to take advantage of this interface.
• Fixed an error in which OPV predictions on small files could get caught in a forever loop and end with an error '6'. The change in 0.73 that forced CBR encoding was not allowing the adjustments.
• Fixed a minor error in which some qual_prec= settings in ECL files were being set to floating point values. Just a cleanup - no real effect.
• Corrected a very elusive error related to flushing information at the end of cells -- could have been responsible for some possible stutter and audio drift.
• Fixed and error in which the "Rewrite Defaults" function wasn't properly updating the graphics files.
• Made code associated with timing adjustments more robust. This will fix many of the #0003, #0004 and #0006 errors experienced. It should also make DVD-RB more compatible with edited files from DVD ReMake and VOB Blanker.
• Added code to trap certain error #52 and '5' conditions caused by an invalid path. These errors are related to DVD ISO images that have been mounted. Some DVDs apparently have hidden illegal file info that forces these errors and causes DVD-RB (and other software) to fail. It should work now.
• Corrected an error in which null packets (generated by DVD Decrypter as a way of bypassing certain protection schemes) were incorrectly being inserted into into the output stream causing Error #0003 (possibly other errors as well depending upon positioning).
• Added a "BatchHeight=X" variable to the [MAIN] section of the Skin description. It makes it possible to relocate the batch box to the bottom of the screen (rather than only the right side). (Rockas rules).
• Added additional QuEnc support making newer versions more compatible. DVD-RB now outputs command line parameters to prevent muxing, which is reported to have been related to errors.
• Fixed an error in which the maximum bitrate was being incorrectly set at only 80% of the calculated value for PAL sources that were being encoded using OPV. Probably little/no impact -- but it's correct now.
• Changed defaults so all segments with less than 60 frames are encoded using CBR. Previously this only applied to half-d1. It seems CCE may have problems applying VBR to some exceptionally small sources.
• Added code to handle IFO cell table entries that reference sections of a VOB that is smaller than a cell (protection?) found on some recent DVDs (e.g. Resident Evil Apocalypse, The Forgotten). DVD-RB ensures the structure remains true to the original.
• Moved the "Verbose Status Window" option to the "File" menu so it is grouped with the other status related options.

• Fixed an error that causes CCE SP V2.50 to create an incorrectly formatted .ECL file and fail in the encoding phase under certain circumstances.
• The GOP size for NTSC material that is not from a FILM source has been changed to default to 15 frames (rather than 12). This should improve quality at a given bitrate on NTSC sources that are interlaced and should be especially useful on episodic discs of television shows.
• Made a correction to the quality prec value for CCE v2.70. The scale has been changed (again) in this CCE version. The scale is again set to 0-100. NOTE: DVD-RB will automatically make the conversions between the scales of different versions.
• Updated the SETUP and ABOUT screens with new images provided by Rockas. Now there is more room available for viewing paths in the "Rockas Original" SETUP screen. You must select "Rewrite Defaults" under the SKINS menu for this change to take effect.

• Added a new option entitled "No Compression (100% Video)" under the "Mode" menu. This option will keep original video intact (no reencoding) and only remove audio/subtitles as selected. This is meant for use with discs that are only slightly over DVD-5 size and can fit with audio removal. It is also a way in which previously created discs can be demuxed and remuxed to fix possible errors (for example buffer overflows or audio dropouts). This mode is very, very fast.
• The default skin "Rockas Original" was completely reworked and is now even more cool than previously. My thanks to Rockas. Make sure to select "Rewrite Defaults" under the "Skins" menu for the fix to take effect.
• Fixed an error in which a newer "Rockas Original" batch background was not correctly included in v0.69 -- which caused misplaced buttons and list box. Make sure to select "Rewrite Defaults" under the "Skins" menu for the fix to take effect.
• Modified the One Pass VBR (OPV) prediction code to more accurately select Q values. The previous method tended to make output too small. Thanks to Robot1 for lending me his code to analyze.
• Added a new default skin called "Simple Blue" It takes advantage of the standard background provided by Rockas. In order for this skin to be available you must select "Rewrite Defaults" under the "Skins" menu.
• Fixed a "disappearing button" problem associated with the Batch "OK" button
• Fixed an error in which changing skins while processing batch jobs could lock out the possibility of interrupting the program -- essentially locking out the user.

• Modified the "working" directory selection algorithm so that when the "output" directory is not enabled it will be automatically updated to match that selected as "working"
• Inserted code making any segment of 60 frames or less that is being encoded using Half-D1 outputs in CBR mode. This should eliminate the annoying "cce_encoding_init() failed" error that sometimes occurs.
• Fixed the alignment error experienced in 0.68 on the setup screen when used with skins.
• Modified the default skin used under "Rockas Original" -- Rockas has updated this skin with a little less brilliant colors and a nice textured finish. You will need to select "Rewrite Defaults" under the "Skins" menu for the new skin to take effect.
• Further tweaked SCR calculations. This fix again adjusts the buffer algorithm further in the "less likely to overflow" direction.
• Added capability so that audio selections are now saved in the rebuilder.ini file in a manner similar to that used in project files. This makes it no longer necessary to reset your audio choices any time you stop and then restart DVD-RB.

• Corrected an error that cause QuEnc to fail due to a "blank" .AVS filename.
• Tweaked SCR calculations to more closely control STD Buffer size. This may reduce or eliminate reported audio dropouts on some players.
• Added "Rewrite Defaults" option to the "Skins" menu. This will recreate the two standard interfaces in the Skins directory. The option is meant to provide a way to correct any mistakes created in editing the files. It can also be used to implement changes I may make to the standard interfaces.
• Fixed an cosmetic error in which some residual color was included in "Folder" buttons.
• Added control over placement of the AudioList, SubList, DTSCheckbox, and MinCheckBox objects in the SETUP dialog box. These were inadvertently left out of the last version.
• To enable the last two fixes -- YOU MUST SELECT "Rewrite Defaults" in the "Skins" menu so the lastest definitions are updated.

• Integrated an exciting new visual interface designed by Rockas. Thanks, my friend. May the road rise up to meet you, and the wind be always at your back. This interface is the first step in enabling "skin" capability for DVD-RB.
• Multiple angles and ILVU (Interleaved VOBU Units) are now supported. The method used has worked successfully on all multiangle and seamless branching discs I've tested to date.
• Note: The greatest challenge I've run into with multiple angles and ILVU is that they are already pretty tightly bitrate bound -- and any smaller sizing at all seems to noticably degrade the quality. So for this version I've decided to not further compress the ILVU portion of a film. In my testing it has shown to not be worth the quality loss -- the largest ILVU portion of a film I've found is the Matrix, and it is too small to have any significant impact on available bitrate. I can readdress if anyone finds a DVD in which this isn't the case.
• Fixed an error in which the "Steal Space From Extras" settings were notloading properly from .RBD files during batch encoding.
• Added a new selection list to the main screen so subpicture streams can now be individually selected. Be careful when removing subpictures, especially when they are shown as "Unk" -- some special features (e.g. "follow the rabbit") rely on subpictures.
• Fixed the Rebuilder form's header -- removed "3" from the title
• Fixed an error in which the Subtitles listbox wasn't visible and could not be accessed.
• Corrected an error in which ReJig encoding failed during the "PREPARE" stage when working on a disc with ILVU and/or angles.
• Corrected an error that incorrectly always set the "Aspect_Ratio=" variable in the .D2V file to 16:9. (No impact noted in previous version).
• Found and fixed an error in which interleaved sources, under certain conditions could redirect the PREPARE and/or ENCODE date an incorrect directory.
• Fixed an error in which Subtitles having an number higher than 9 would be incorrectly shown out of order in the "Subtitles to Keep" listbox.
• Added support for "Skins" -- user programmable definition files can be created that load backgrounds, set text, and allow you to customize the way you want DVD-RB to look. NOTE: When DVD-RB is executed it will automatically create a SKINS directory within it's execution path! Several default files will then be created in that directory... these files define the default skins. Two defaults are provide. "Rockas Original" is the interface you've seen, as it was released in version 0.65. Also provide as a default is "Windows Standard" which is very similar to what you would have seen in version 0.64a. You can modify them, customize them, do whatever you want... but remember if you ever run into problems you can always delete the files -- and DVD-RB will recreate them the next time it is executed. You can use the two default skins as a baseline for new ones you create. Simply copy the files, rename, and modify and you can play to your heart's content. The name you use (e.g. "My Skin.txt") when creating a new file, will be added to the "Skins" menu the next time DVD-RB is executed. The SKIN code is new -- so some beta problems and feedback is expected. Enjoy.

• Added support for DGDECODE.DLL. This is a newer, more accurate, and faster version of MPEG3DEC3DG.DLL. In order to use it, download DGMPGDec from the Doom9 site (the only required portion of the .ZIP file is DGDECODE.DLL. You must point to the file from DVD-RB's "Setup" dialog. The MPEG2DEC3 path area name has been changed to "DECODER". NOTE: In order to use DGDECODE.DLL you MUST point to it in the DECODER area of the setup dialog and it must not be renamed (from DGDECODE.DLL). DVD-RB will default to MPEG2DEC3DG.DLL. Hats off to Neuron2 (Donald Graft) who is an MPEG Maestro.
• Removed the "Add to AVS" checkbox from the setup screen. It was a source of confusion and probably should never have been implemented. If you enter a path in the "Path to Decoder" box -- it will be loaded in every AVS file.
• Created a new option under the "Mode" menu that allows you to use a different "Output" path. When selected, the output of VIDEO_TS and AUDIO_TS folders will be sent to that path rather than the "Working Path." This allows users who are low on drive space and have more than one drive to write to two different areas. It also cleans the output up a little -- reducing confusion as to which directories should be burned. You burn only what is in the output directory. If may also increase the rebuild speed. If the option is deselected, DVD-RB will work as it always has -- writing all output to the "Working Path."
• Fixed an error in "Batch" mode in which some parameters from the saved .RDB file were being loaded and set incorrectly.
• Note: It continues to be my intention to provide this package as freeware. But it is my belief that I should somehow reward those to took the time and effort to contribute to this project, either through donation or extraordinary testing support. In the future all new releases will be made to a list of VIPs/donators first. After some period (maybe 30 days) that version will be released in a "public" version. Those who helped through donations and special beta support deserve recognition. This is my way of saying "Thanks." THE FIRST DONATOR RELEASE (IN A COUPLE OF DAYS) WILL SUPPORT MULTIPLE ANGLES AND ILVU (I've completed it and am testing it now).
• Fixed an error in which the "Transcode" button disappeared when selecting/deselecting the alternate output directory while in one-click mode. Silly mistake.

• Disabled runt VOBU code for more testing. It appears to have caused more problems then it solved.

• Corrected rebuilding code to prevent "runt" VOBUs (less than .4 seconds). This will bring the newly authored stream more tightly into compliance with DVD standards. This is KNOWN to have caused audio/video stutter on some DVDs.
• Added support for Canopus ProCoder through Robot1's EclPro utility. Nice work Robot1, you continue to provide outstanding support to the DVD community! Please note that this feature needs testing.
• Modified the maximum bitrate on output so it lowers to accomodate large and multiple audio tracks. This should help to keep the bitrate bursts under DVD maximums. Maximum bitrate is now set to MAXBITRATE - AudBitrate -- so using the default it would be 9,000Kbs - AudBitrate. Note that DVD standard is no greater than 9,800Kbs for video and no more than 10,008Kbs total audio/video/subs.
• Corrected a bug introduced in v0.61 related to audio/video sync. This could have caused stutter and audio dropout on some DVDs. An option has been added to the "Options" menu called "Special Error Avoidance" for special cases in which certain #0003 or #0004 errors are encountered -- this is temporary and will be removed in future versions. It is recommended that this option only be used as a last resort after you've encountered one of these errors -- and not before, as it can cause other unpleasant effects. This option ONLY affects the rebuild phase. It is meant to counter what appears to be bad source timing parameters.

• Added an option under the "Help" menu that will display the versions of support software you are using. This should be useful in debugging problems.
• Inserted code to modify the sequence header extension on NTSC telecined titles so that the progressive flag will set to 0 -- this was noted as a problem associated with QuEnc. Please note that this DOES NOT mean progressive streams will not be recognized and played as progressive. This should fix reported "stuttering" on some players when using QuEnc as the encoder.

• Found and corrected a cause of Error #0003 and #0004. This should fix most reports associated with these errors. Note: Remember some are caused by invalid source files.

• Fixed an error in which users of CCE v2.67.0.27 Trial/ECLCCE were getting the wrong ECL settings.

• IMPORTANT FIX: Corrected an error in SCR/PTS computation for audio and subpicture streams. Likely symptoms of the problem that was fixed is audio dropouts, and stutter. It may also have and affect on Error #0003, and Error #0004. My thanks to fritzdis and Sir Didymus for helping find this. Note: Do not simply try to "REBUILD" old sources, this fix includes a change in the "PREPARE" phase.
• Corrected implementation of version checking for CCE. v0.59 made an assumption that new CCE ECL changes applied to all 2.67 SP Retail versions. It has been modified to now only apply to CCE SP Retail v2.67.0.27.
• Corrected a problem in which reopening DVD-RB after receiving a "..multiangles" error would allow it to process the selected fileset -- even though it would always result in an error.
• Fixed an error in which the last audio pack within a VTS was not being written to the output stream. This could cut a very tiny (~40ms) from the very end of a movie. Thanks to totya for pointing this one out.

• Found an additional System Clock Reference (SCR) error that caused some NAVPACKS (immediately following a sound or subpicture packet) to not comply with the DVD minimum spacing standard. This, depending upon the player, could theoretically cause any of a number of audio, video, or timing problems. This has the potential of being a very big correction. A special thanks again to Sir Didymus and the Doom9 beta testers.
• Fixed an error that was responsible for random but rare #0003 errors depending upon original source timing characteristics).
• Added code that forces GOPSIZE to a DVD standard when using QuEnc.
• Fixed a problem in which version update checks were not being recorded when changed in the SETUP dialog (only on startup).
• Fixed an error related to PES headers in which the P-STD Buffer size data was not being properly set at the beginning of each data stream.
• Corrected an error in which stuffing bytes at the end of a stream could overwrite PES header data (a million to one -- but possible).
• Added two more choices to the "QuEnc Options" menu. You can now choose to enable High Quality Mode (slow but very impressive quality) and "Use Scene Detection" which makes intelligent decisions as to where to break GOPs. For those who haven't tried QuEnc... it has become the highest quality encoder available as freeware -- and outdoes most of the costly alternatives. Hats off to Nic and dragongodz.

• Found and fixed a source of Error code '9' that can occur immediately at the start of an encode.
• Made changes to the output ECL formats so CCE SP version 2.67.xx.xx retail versions are supported. Please note that SP 2.67.xx.xx Trial version will only work with ECLCCE.EXE. Do NOT attempt to use ECLCCE.EXE with the retail version of 2.67.xx.xx -- it isn't needed, and doesn't work. Note: I don't have a copy of the retail version to test -- but I believe it will work.
• Found and fixed an error in which certain circumstances could cause illegal System Clock Reference (SCR) values near the end of some cells. This could very possibly have caused audio problems and/or video problems on some standalone units. Special thanks to Sir Didymus for identifying this problem.

• Updated code for compatibility with QuEnc 0.52 and above. The KVCD commandline logic has been replaced by the QuEnc Lower Bitrate (QLB) Matrix option. Older versions of QuEnc will no longer be supported and will get an error if use is attempted. QuEnc 0.52+ is free and is easily found on the net.
• Corrected an error in which the progressive flag was not being set correctly during rebuild when "Deinterlace with Decomb" is selected. Also please note that if the input stream is already identified as progressive, the deinterlacing filter will not be added to the associated .AVS file.
• Modified SCR algorithm to more accurately reproduce the SCR/PTS structure of the original disc.
• Made a timing correction that may affect possible audio dropouts. It also may reduce (but not eliminate) the liklihood of encountering an error #0003 or #0004 on preprocessed (3rd party edited) streams.
• Fixed an error in which the "Disable Interlaced" was correctly reencoding the as progressive -- but was incorrectly reinserting the original flags on rebuild.
• Add a "Status Logging On" switch to the file menu. When checked, anything that is output to the status box is also echoed to the log file. The file, called "rebuilder.log" is created in the directory specified in "Working Path" -- it no path is specified it is created in the root of the C:\ directory. The file location is changed whenever a new working path is specified (for example when running a batch job). This should be helpful in debugging problems that might cause DVD-RB to exit abruptly.

• Fixed an error in which VTSs with very few frames could result in Error Code '6' when using OPV mode. These now default to a Q Factor of 10.
• Changed the size of the "Source Path" and "Working Path" areas so longer filenames can be viewed.
• Fixed and error in which the PTM of the last frame of the last GOP of a VOB was sometimes incorrectly calculated and placed in NAVPACKS. This, very probably, was the cause of reported "freezing" on some Sony players.

• Fixed an error that made DVD-RB fail to run in Windows 98 and SE versions. It should now work properly on all versions of Windows. Thanks to turbodpv for catching this -- and to wmansir for his help in identifying the cause.
• Adjusted the OPV calculation so that it better predicts size.
• Fixed an error in which the reallocation of recovered space associated with "Half-D1/Half Space" and/or "Steal Space from Extras" was not being allocated correctly with certain combinations of the switches. This was the cause for reported oversizing/undersizing.
• Added informational parameters to the REBUILDER.INF file related to original DVD overall and VTS sizes (in sectors) for use by helper applications.
• Corrected an oversight that has been in the program since v0.36. Subtitle streams were not being updated in the IFO PGC tables when converting from 4:3 to 16:9. The result was the inability to view any but the first subtitle (when a 4:3->16:9 conversion was done).
• Implemented code that corrects the way selected audio streams are saved and recovered in project files. Now any non-standard (different from that recorded in the setup configuration) audio choice is recalled on project load. This also works in batch mode.

• Corrected error in which the "all contents of VIDEO_TS..." message was not suppressed when "Suppress Warning Prompts" was selected. Thx to jhmac.
• Changed output to .ECL files so "seq_endcode=1" is set for still frames this has been reported to fix problems associated with stills and BOV. Thanks to wmansir and Sir Didymus for researching, finding, and testing this fix.
• Corrected an error associated with CCE Basic that caused a "cce encoding failed: MPVA ... qsv 112 > 112" -- caused by an average bitrate that was calculated to an exceptionally low value.
• Fixed an error in which only the last two digits of the segment number were displaying in the status window. Thanks to jptheripper for catching this.
• Fixed error in which the the "Shutdown" options were not working correctly with Windows 2000 computers (stopped at the "SAFE TO REMOVE POWER" prompt). Thanks to archaeo for pointing out this error.

• IMPORTANT BUG FIX. Fixed an error in which original (unchanged) files were not being copied correctly into the destination directory. This could cause created directories to fail upon write.

• Corrected an error in which the prediction phase of OPV could get into a continuous loop when a change in Q of 1 might result in an output that was still not within 1% of the target.
• Changed logic so all still frames are output as Constant Bitrate (CBR) in an attempt to correct some persistent CCE related still/BOV problems.
• The "Quality_Prec=" value set in the CCE settings dialog is now also used to adjust the "pict_qchar" value that has been introduced to CCE Basic starting with version 2.69. Please note that (as in CCE SP 2.50) the value is scaled between 0-64 (to match newer versions of CCE SP) and will be converted to a value of 0-100 when written to the ECL file.
• Corrected an error in which the "Steal Space From Extras" options were showing as having an effect (messages were presented) when "Dynamically Assign..." was not selected. The "Steal" option only works with "Dynamic..." is selected.
• Set several "warning" messages so they would not display during batch mode encodes (follows the same logic as having the "No warning" flag set).
• Adjusted audio and subtitle language tables to account for apparent differences between the current ISO and DVD standards. Two types of codes (old and new) are accepted for Hebrew ("he" and "iw"), Indonesian ("id" and "in"), and Yiddish ("yi" and "ji"). Thanks to HARM for pointing out this inconsistency.

• Corrected an error in NAVPACK processing that may be the source of at least some of the subtitle problems some have reported with certain players. The PTM of the first and last frame in a VOB was not being correctly updated.
• Implemented improvements to OPV algorithms. Now have more consistently accurate prediction of filesize and predictions are now made in fewer passes (2-3). As there are typically fewer passes now, the default sampling percentage has been increased from .5 to 1 for improved accuracy. Also added two INI entries: Q_sample_percentage=n (default is 1, can be set to any value from .1 - 25), and Q_ROM_constant=n (default is 256, with max/min of 300/200. You may be able to get better accuracy in some cases with Q_sample_percentage set to values higher than default -- but it will in turn add significantly more time to the prediction process and the PREPARE phase. Q_ROM_constant is used to estimate a Rough Order of Magnitude (ROM) Q value for the first pass using the formula:
  Q = (framecount / targetsectors) * Q_ROM_Constant
  A special thanks to tylo, author of D2SRoBa, for reviewing the DVD-RB algorithm and recommending some excellent improvements.
• Added an "Are you sure you want to abort?" prompt during encoding to help prevent accidentally aborting when doing other work while an encoding session is taking place.

• Corrected a problem in which, if you did not go into the setup screen and specifically choose default subpictures to remove, all were removed. Bad day.
• Added an Expert AVS option in which you can add text that will be added to AVS files. This is meant to support filters -- but can also be used to activate other AVISYNTH commands. This is an EXPERT OPTION. If you are not intimately familiar with AVISYNTH... leave it alone. It can make your encodes fail completely if incorrectly used. Note: Don't use blank lines.

• Added Subtitle removal to the SETUP dialog. You can now make a global choice as to which subtitles remain or get removed. Space recovered from removed subpictures is reallocated to the main movie (as is true with audio). In this version the subtitles will still exist in the IFO files -- but are removed from the VTSs. Future versions may remove them from the IFO as well.
• The bitrate fix in v0.50 was incorrectly implemented. Progressive and PAL sources were getting maximum bitrate reductions while those that should have been receiving the reduction were not getting it. It has been corrected. Thanks to Brikin and The_Flash.
• Enabled the "Steal Space from Extras" option. This option allows you to improve your main movie quality by reducing the quality of extras. It works by taking storage space (25%, 33%, or 50%) from whatever is in use by the extra and then reallocating it to the movie. Please be careful in using this option -- as it can very easily degrade the quality of extras to an unacceptable level. It is really meant to be used when extras take a LOT of space on the original disc. Also please note that the reallocation of space happens BEFORE other options -- so, for example, if you choose Half-D1/Half-Space and also choose 50% reduction, the Half-D1 size will be halved twice -- resulting in a Half-D1/One-Quarter space. This option is only valid when the "Dynamically Assign Cell Bitrates" option is enabled.
• Modified One Pass VBR mode so it recovers sectors associated with ReduceBy and Half-D1/Half-Size options. The recovered sectors are now added to the target sector size associated with the main movie VTS.
• Fixed error in which the maximum bitrate was not being set for PAL interlaced output. Thanks to Amenophis for finding this.
• Modified the rough order of magnitude calculation for beginning Q in OPV. It should take fewer prediction passes (on average).

• Did some tweaking on the One Pass VBR. Should be closer, still needs work.
• More tweaking of the One Pass VBR. It's starting to look good.

• Corrected an error in which the maximum bitrate could peak higher than that set in the max_bitrate setting when working with interlaced sources. This is highly likely to have been the source of infrequent frame stutters at high demand points in encoding. The problem is the result of DVD-RB's inherent method of feeding frames to CCE and QuEnc. Please note that if you browse the .ECL files for interlaced sources, they will now show a vbr_brate_max= value that os 80% of the default setting -- do not change it. It is right, and the resulting stream (after processing) will still match the max value. Excellent observation by Trahald.
• Added a One Pass VBR mode for those who are using CCE SP. It performs sampling pass(es) during PREPARE phase that predicts an appropriate Q rating based upon the space available. That Q is then used for a one pass encode. Total time for an encode is reduced dramatically while quality is maintained at a known level. This is the first iteration of this set of routines and its still being tested, so some level of sizing error is expected. Please provide feedback in the DOOM9 rebuilder forum. Note added: It seems to be oversizing consistently. I will do some mods and post a fix soon.
• Fixed an error in which answering "No." to "Continue" in the PREPARE phase would result in the encode and rebuild buttons remaining disabled (regardless of their previous state). Thanks to wgw for finding this one.
• Added more timestamps to the Status messages to make it easier to determine the lengths and times of different activities.
• Fixed an error in which having "Shutdown at One-Click Completion" selected while using batch mode would terminate Rebuilder after the first batch job. Added a "Batch Shutdown" option to the "File" menu that now the system can be set to shutdown following a batch run. The setting is NOT saved to INI and will not be persistent across program runs (purposefully).

• Fixed an error that could cause audio drift over time, cell audio moving out of sync, and also was responsible for some (rare) "freezing" chapters. Thanks to Djuby for pointing out a disc through which it was repeatable.
• Fixed a minor error in which during save the wrong extension is shown (".RBD" showed as ".RDB").
• Corrected processing of Project Files. When loading the status (such as noting that PREPARE is complete) was not retained and updated. Thanks to maksa for pointing these last two out.

• Corrected an error related to fast forwarding and rewinding through chapter points. The first entry in any Cell's first DSI was not correctly flagging time offsets that had no prior VOBU. My thanks to Sir Didymus for finding and pointing out this error. Extraordinary beta testing!
• Added support for the "-maxbitrate" option to all QUEnc encode command lines. The value is set to the DVD-RB default of "9000" unless changed via the "max_bitrate=" INI option. This might fix some of the stuttering errors seen when using QuEnc.
• Enabled checking that disallows mismatching of modes between the PREPARE and ENCODE phases.
• Fixed an error in which "IDCT7" was not being properly applied when selected. Thanks to djan for discovering this error.

• Updated code so subtitle support is more properly implemented. This should fix most (if not all) of the problems associated with non-displaying subtitles.
• Again tweaked the monitoring of CCE to try and improve performance on multi-threading processors. The parameters posted with 0.46 were too conservative.
• Added automatic addition of the -interlaced or -nointerlaced command line option to QuEnc. The determination is based upon data found in DVD-RB's PREPARE phase.
• Added an option under the AVS advanced menu setting MPEG2SOURCE("source",idct=7) as a possible default.
• Fixed an error that caused incorrect calculation when Half-D1/Half Size option is selected. This generally resulted in undersized output.
• Fixed an error in which the "TargetSectors=" INI command was not being used to establish a default when targets were not established for the selected encoder.
• Other minor corrections and optimizations were made.

• Added support for Button-Over-Video. Imbedded menus and user actions should now work correctly. This also sets the stage for possible menu size reductions.
• Found and fixed Runtime Error '9' that occured during REBUILD phase. This should end most if not all of the '9' errors. It will be especially noticable in removing them in Half-D1/Half-Bitrate extra selections.
• Fixed a source of Runtime Error '9' in PREPARE phase.
• Found a situation in which bad MPEG editing in the original DVD (in which trailing B frames were deleted leaving an out of temporal sequence I or P frame) could cause error #0006 in REBUILD during transcoding (using ReJig). A workaround was implemented in which the temporal sequence was adjusted.
• Changed code so the "PREPARE" button doesn't change to "Process" after running it the first time. It wasn't supposed to.
• Made a modification to the monitoring of CCE as it is running in an attempt to get it to apply less processor time to DVD-RB when running on multithreaded processors. On my Athlon 2400+ processor it has dropped to consistently less than 1% processor usage for DVD-RB while CCE is running.
• Reset the DVD Compliant flag to "off" in the ECL files to bypass a new "feature" associated with CCE's 2.69 version. If it is set "on" CCE tries to outsmart you and add frames to a 23.976fps source.

• IMPORTANT NOTE: Ensure you are using DVD Decrypter version 3.2.1.0 or above. Version 3.2.0.0 (and possibly below) in ISO mode can cause "illegal input stream", "no I-Frame for 51 frames", and "Runtime Error '9'" due to a bug in it's ISO mode processing.
• Corrected Error Code #0004. Rebuilt the NAVPACK decision engine so it handles large streams of non-video data that is sometimes associated with STILLs.
• Modified the 4:3->16:9 output for interlaced sources so fields are separated prior to resizing and weaved back together after resizing. It should make for a more accurate representation of the source material.
• Found a error that could cause DVD-RB to exit with Runtime Error '9' when it encountered an illegal input stream. The error is now properly recognized and DVD-RB gracefully aborts the PREPARE process.
• If you are going to use QuEncode with DVD Rebuilder -- you must upgrade to QuEncode v0.47 or above.
• Added an option under QuEnc that enables single-pass encode as an option.
• Modified the source to take advantage of the new QuEnc version Nic has released (v0.47). This version that supports better DVD-RB control over options -- they can now be reset after setting (Trellis, KVCD, and 2-pass).
• Added a "Shutdown at One Click Completion" mode item. The state of this flag is not kept between program runs. It will do a Windows Shutdown at the completion of the next One-Click execution. A 10 Second warning window enables cancellation before shutdown.
• Numerous other minor changes, enhancements, and bug fixes including modified handling of some sound and still images.
