I'd advise you to do an extended search over the net ... if you really want it
Ds.jar works BETTER than pvastrumento & Co. It has a better error management and it perfectly synch audio and video.
For example if you demux using DVD2AVI (or other prog), when you find a broken frame, you'll get a small delay of audio. In my tests, in a 2hr capture you can get a lot of bad frames, so audio will delay about 5 or more seconds.
