I have tried to rip 2 DVDs using smartripper in the last few days and had the same problem each time.

The discs I attempted to rip were: Thumb Wars (Star wars parody)
Westlife - Unbreakable (girlfriends!!!)

Both times I was able to rip part of the vob list, but not others. Some files play perfect on Power DVD, and will pass successfully thru DVD2AVI and TMpegEnc. Other files turn green and severely pixellate, and have poor sound quality. Have tried DVD Decrypter, but many of the files I want cannot be got thru decrypter, as it only looks for the largest movie

Any suggestions?
