These have free GUI's that you can you can use....jus follow tha directions and read everything..if i remember correctly you have to only get VOBrator and DVDdecryptor and your set.....Good luck!
you should have oudio outs on your tv. if the dvd is hooked up to your tv just connect the tv to your computer audio in, and hopefully u have a pogram on your computer that u can record the audio coming in.
just take your dvd in the lab with a 13 inch tv. make sure tv has video in jacks on the back or front. plug 1 end of the cable in audio out on dvd and the other end of cable into the machine you are using to sample with.
