Devidify application can help you to extract audio tracks from DVDs.
I wrote it because I had a few concert DVDs laying around, and wanted to get their audio tracks into my portable music player. At the time, existing Linux-based tools meant ripping the video first, then extracting the audio. They made none of this easy. Who has time for such nonsense? Devidify makes things easy. Feed it a shiny disc and it spits out WAV, MP3, or Ogg Vorbis files.
