How is it that WinFast PVR creates an MPEG 2, DVD compliant video (from VHS) that plays perfectly on the PC, but when I try to author it with tmpgenc dvd author it always comes out with synch issues?

TMPGenc dvd author imports the a/v stream perfectly. I can preview and edit, and all plays in synch. It's only after the authoring that it goes off. Starts at about the 10 minute mark and progresses to about 2 seconds by the end of 1 and a half hours.

I'm using fresh install winxp pro, 80 gig hd defragged, 768 meg 2100 ram, 1800+ cpu.

This is getting frustrating.
