I'm assuming the original VOB did not go out of sync at the same point? Is it out of sync for the rest of the film? That's correct. The process was like this:
1. DVD Lab to join the original VOBs from the TR47 DVD into one VOB named DVD Lab's default name when doing this, "join.VOB".
2. VideoReDo (hokey non-resizable GUI and I'd never heard of it but it did what it claimed it could do) to open "join.VOB" and accurately delete the 4 seconds of black screen and save results without re-encoding. It saved with the MPG extension so the file name is now "joined minus black screen.mpg". Playback of this file showed it to be exactly what I wanted. The cut edit was perfect and the audio was still in perfect sync throughout the entire movie.
3. DVD Lab to recreate the DVD from the 4.33 GB "joined minus black screen.mpg" file without re-encoding. I did try it without demuxing which was against DVD Lab's popup warnings and when I went to complile the DVD it sat there saying it was "checking streams" or something like that, for a couple of minutes and then it claimed it was "done". Well it obviously wasn't "done" because 2 minutes isn't even long enough to simply copy a 4.33 GB file from one location to another on my machine. When I checked the destination folder, all it had done was create empty VIDEO_TS and AUDIO T_TS folders along with a 0 byte VOB file in its temp directory. So, I loaded "joined minus black screen.mpg" again and let it do everything it was recommending, i.e. demux into elementary streams and also convert the LPCM audio to WAV. I added the chapters and compiled the DVD which consisted of muxing and setting navigation parameters. The finished DVD was in sync for the most part. In the first Lando and Han scene it went out of sync and then back in sync several minutes later. It may have gone in and out of sync more than just there but I didn't sit down and watch the whole thing; I simply scanned through it.
Don't knock DVDLab Pro for this. I, for one, love the compliance checking. Keep in mind that you can for DVDLab Pro to *not* demux the files. You might want to try this, or even have DVDLab join the VOBs for you.
I'm not knocking DVD Lab for that; in fact, its ability to create a DVD from DVD compliant files without re-encoding is why I used it in the first place. I am beginning to question the accuracy of its muxing/demuxing abilities however. 1.

My only guess would be that there was an error in the audio file there, or an error in the extraction (did you try it more than once?). You might want to run the VOB through VOBrator, extract the audio as a WAV, and load the WAV into DVDLab Pro.
I only demuxed the "joined minus black screen.mpg" file once. I have never used VOBrator, but I could also demux to a WAV with VDubMod or I could run this original LPCM file through BeSweet to get a WAV. That will help pinpoint the problem I guess. Don't knock DVDLab Pro for this. I, for one, love the compliance checking. Keep in mind that you can for DVDLab Pro to *not* demux the files. You might want to try this, or even have DVDLab join the VOBs for you.
