I downloaded a movie from the net. It was an avi, so I converted it to mpeg using tmpgenc. After I converted it the audio and video were fine. There was a problem with my DVD creating software, so I demuxed it and got a m1v and a mp2 file. I then used ifoedit to convert them to vob files. But now, the video is way ahead of the audio now. What is the problem and how can I fix it? Also, I use sonic myDVD to make dvds, and it sucks. What is the best and easiest authoring software to use?
