I don't know anything that rips in DivX or XviD, but my favorite DVD rippers are:
Handbrake - Rips and converts.
- File format: MP4, MKV, AVI or OGM
- Video: MPEG-4 or H.264 (1 or 2 passes or constant quantizer/rate encoding)
- Audio: AAC, MP3, Vorbis or AC-3 pass-through (supports encoding of several audio tracks)
DVD Shrink - Rips and compresses. Compresses the video so it can fit on a single layer DVD.
DVD Decrypter - Rips. The site recommends using AutoGK to encode to XviD after ripping.
