I converted an AVI to MPEG using TMPGenc and the video and audio are sync'd perfectly. When burning it to a DVD-R using Ulead Workshop, the audio plays at normal speed but the video is at a higher rate of speed and gets ahead of the sound by about 5 to 10 seconds. I tried it on my PS2 and it did play, but had the sync prob with that and my computer's dvd player. Any suggestions!?
