I have encoded several of what I thought were DVD compliant videos using TMPGeng with the half KDVD templates (www.kvcd.net). The resulting MPEG is perfect when using PowerDVD to view, the problem is when I go to author the DVD. The resulting DVD has audio sync issues, I've tried using Ulead DVD workshop, Ulead moviefactory, etc., with recent patches and end up with same result, audio slightly out of sync (drift, starts out in-sync and then slightly loses sync). Is anyone else having these issues and does anyone know of any solutions out there or what causes the audio to lose sync? Please help!!!
