Is dvd::rip really this bad? Or is it that people don't know how to use it? Did you know that all you need to do to rip a dvd is this:
tccat -i /dev/dvd -T 1,-1 >mymovie.mpg You will get the video, all audio tracks, and all subtitle tracks (for title 1, in this example). If you are transcoding from dvd/vob/mpeg2 and getting sync problems, it means that you are dropping audio or video frames, so you need to change the options that you are using to do hard frame duplication, (copy null frames) instead of soft (frame dropping). Also, I haven't pointed this out for a long time here, so let me reiterate: Video transcoding is hard to do right. There is no magic tool that will do what you want reliably 100% of the time. Ciao.

Why is it not possible to use avisync directly ?
