Hi,
I'm collecting episodes of an animated tv show (captured and downloaded) I run'em through a feew filters in vdub then convert them in tpmgenc then burn'em w\roxio.

Some come out fine, while others get out of sync, it starts normal but then gradually the video moves ahead of the audio, and it keeps getting worse and worse .5seconds difference mid way , 2 seconds near the end.

any advice?
