This software, while very easy to use, and while producing very good quality, has a couple of things which might need to be addressed. I used this software to produce both SVCD's and AVI files from DVD's for a long time before deciding to try DIKO.
First, I have always had trouble with Audio/Video Sync when using this software to produce SVCD's. Second off, the SVCD's produced were of considerable size, while DIKO compresses most movies into the space of 1 CD, DVDx normally takes 2 or 3. Other than that, it's great software, and normally works seamlessly.

This has got to be the ultimate DVD/AVI to KSVCD/KDVD software! You can use either and AVI source, or use a raw DVD Rip. Like it says, everything you need to create standard complient MPEG-II streams comes with it, including DVD Decrypter, to rip DVDs to your hard drive, and DVD2AVI, which you can use to quickly and easily create the D2V files DIKO uses to process the DVD rip and create the MPEG-II video. Once the D2V files are created in the same directory as the ripped DVD, just select them in DIKO and go! On my 1.1 Ghz Athlon, Encoding a full length movie takes about 4 hours. The one thing that makes DIKO so great though, is that it compresses most full length movies (depending on the movies length) into the space of one SVCD (around 700 MB), requiring only 1 CD per movie, while still keeping high quality audio and video! In the case that a movie is extra long, you can change the media count to 2, and it automatically splits the MPEG-II video into 2 seperate files for you, moviename.mpeg.cut.1 and moviename.mpeg.cut.2. Just rename the files and you are ready to burn.
I used to use DVDx to make SVCD's, but now I use DIKO and nothing else. It is excellent, easy to use software that produces compact, high quality video streams that can be burned as a SVCD and played on most modern DVD players. GET THIS SOFTWARE!
