RATattack is a set of tools for making it easier to create and maintain ratDVDs. It contains the following tools:

RATdecrypt:
This is a ratDVD Import Plug which extends ratDVD to automatically decrypt CSS in the background when you encode from DVD to ratDVD.

RATcheck:
This is a small tool that basically reads through the full ratDVD file and makes sure all ZIP entries are OK and the checksums match. It is very handy if you want to check if a ratDVD is really complete and not damaged.

RATbatch:
This is a program that does batch processing of DVDs into the ratDVD format. So, if you have a lot of DVDs you want to convert, this is very useful instead of doing it one-by-one. It goes through a whole directory structure and converts every DVD image it finds to a ratDVD in a given target directory. You can even specify the transcoding method and the quality/bitrate. It also supports the ratDVD profiles.

Also included in the RATattack package is the patched version of Media Player Classic which supports ratDVDs with full navigation etc.

Make sure you download ratDVD as well!
