Well www.videohelp.com is a good site for help with anything video, hence the address. You can set DVD Decrypter to rip to a single VOB file instead of splitting at 1gb as they usually do.

Otherwise you could perhaps use DVDShrink, which lets you re-author in such a way that you can specify the particular video you want from the disc (main feature, bonus features etc) and a start and end point, aswell as which audio tracks to use.
