I have been using an Adaptec Vide-OH! PCI card and MyDVD to capture. It has actually done quite well for me and I have used it for some time. I use DVD Author to build my DVD's and it works great. Most of my capture is from Dish and that's fine. However, I bought some region 2 versions of a TV show a few years ago and a modified DVD player to watch them. I have been capturing those episodes to burn them to Region 1 (their available for R1 now so there is no legal issue). I have transferred about 250 10 minute video chapter files and three are giving me a wierd problem.
I play the captured files in WinDVD, WMP, MPEG2VCR, and others and it plays great. However, in the "Chapter Cut Edit" setup of DVD Author, if I play the clip from the beginning, there is a sync delay in the audio. This shows up in the DVD, also. Here's the kicker: if I scan forward to a given scene and play it from there in DVD Author, the sync problem disappears. That's how I missed it, originally. It only shows up in DVD author if I play the clip from the beginning. Further, editing the clip to remove the first few frames does not help. The sync problem remains.
I found one solution to this on the web was to convert the mpeg to a new one through Showbiz. This works but the resulting video contains jitter and is unacceptable. The standard process of correcting a constant (not progressive) sync problem is to resample the video with an audio offset. I've done this many times successfully. Unfortunately, in this case, I have no tool that actually sees the sync problem. It only shows up on the burned DVD and in the Chapter Cut Edit tool of DVD Author and only if I play the clip from the beginning.
Here's a wierd twist. If I convert the mpeg to a new mpeg for DVD using TMPGenc Plus 1.5, the sync delay shows up on all tools. I could then use this to resample again with an audio offset but I have discovered that multi generation files have unacceptable quality.
Does anyone have any suggestions on the wierd sync problem?
