1. Rip in DVD Decrypter, in IFO mode (file splitting set to NONE in options).
Note: If your disc is somehow copy protected with new technology, this will be harder. (Rip in DVDFab 5, burn ISO image in ImgBurn from ripped files, mount ISO as drive with DaemonTools Lite or Gizmo Drive, then open this virtual drive in DVD Decrypter. Whew!)
2. Open VOB files in TMPGEnc's MPEG TOOLS, one by one. On the non-simply demultiplex, double click audio stream you want, save it.
3. Convert the audio stream from whatever it is (AC3, MP2, probably) to MP3. You can use something like GoldWave, Belight/Besweet, FFMPEGGUI / HeadAC3he, and several other methods.
4. Burn new MP3 files to CD-R as data, should play fine in most all MP3-capable DVD players, or MP3 players.
