Extract audio tracks out of a video DVD appeared to be a one liner in Ubuntu. Command line power!
for i in {01..11}; do mplayer -vc null -vo null -ao pcm:fast -ao pcm:file=output$i.wav -chapter $i-$i DVD://01; done
The previous example extracts audio from chapters 1 to 11 and store them is wav files called outputXX.wav
