QuickRip is an easy-to-use DVD ripper for UNIX written in Python. Release 0.7 adds the ability to rip with one-pass, two-pass and three-pass encodes, and to resize the video for PDAs. Lots of bugs have also been fixed, and the code has been improved, as a result of a new developer (J. Vargas) working on the project.
