Personally , I dont see the point of ripping a whole DVD , video & sound , you'll be left with a massive .avi file on your hard drive only to extract a bit of the sound .Another easy method I've used in the past if you have a walkman type tape recorder , I use a Sharp mini-disk recorder for this [as the sound is top quality ] ,is to play the desired DVD in your DVD player , attach a lead [2 phonos to 3.5mm jack plug ] from your DVD player to your mini-disk or walkman and press record on the recorder . Once you have captured the track/song etc you want ,just play it back through the PC sound card and capture using Audacity or something similar . It cannot get any simpler than this without all the ripping fuss.
