You can use the media-video/mplayer package to rip the audio tracks from a dvd:

mplayer -vo null -vc null -af resample=44100:0:0 -ao pcm:file=track_1.wav -chapter 1-1 dvd://2

This command will save the audio track #0 of chapter 1 (-chapter 1-1) of the second title (dvd://2) to a wav file named track_1.wav. Use the lsdvd command to find the right audio track/chapter/title combination
