I have a .mpg file with an MPEG2, 6400 kbps VBR video stream and a 224 kbps MPEG1 layer 2 audio stream. I have tested it in media player. I can jump around to different positions or play the whole thing straight through and it plays fine, with the audio in video in synch. I have attempted to author it about 5 times in both ULead Movie Factory 2 and TMPGEnc DVD Author (using a rewriteable luckily).
The first several times I tried creating chapters, and each time the results were the same: the dvd would play fine until a specific chapter, and then the video would jump ahead of the audio about .5 seconds. It would remain that way for the rest of the dvd. Then I tried authoring it with TMPGEnc without any chapters. Just popped in the .mpg, hit author, and burned. The same result happened, at right about the same position in the video where that chapter would have been. So I'm guessing the chapter insertions didn't cause the problem. I was wondering if the burning had anything to do with it, so I checked the VIDEO_TS folder that was created on my hard drive, renamed the first .VOB (which contained the point of error) to .mpg, and played it in media player. Sure enough, the audio and video went out of synch at the expected spot. So now I'm pretty certain that when TMPGEnc DVD Author takes in the error-free (at least during media player playback) .mpg, it screws up the video/audio synch during the VOB creation process.
So I tried it one more time in ULead, without chapters, and without actually burning. I just wanted to test the authored VOBs. So I renamed the first .VOB to .mpg again, and opened it. Good lord it didn't go out of synch! Sweet! I tried playing all the .VOBs and they all played fine! Awesome! Annoying that Ulead works for this and TMPGEnc didn't, because I like TMPGEnc's interface and menu creation process better, but at least something actually sort of worked. My next step is to actually burn the chapter-free, Ulead-created VIDEO_TS folder and see if the dvd will play without synch problems. Then I'll try adding chapters and re-author and burn. I pray that will work.
I realize TMPGEnc DVD Author could be screwing up just because the .mpg may have errors that aren't noticeable in media player (I've heard software players can fix synch problems as they play), but if the VOBs it creates have errors that do show up in media player, then that at least proves that it does something bad during the .mpg-to-.vob conversion, which sucks.
Anyone have any comments or similar experiences? I'm interested to know if there's any way to fix these errors.
Thanks for any input,
Brent
