I don't think so. The video timestamps are pretty regular, every 480ms (one per 12 frames). MPEG and AC-3 audio timestamps are in 144ms and 160ms intervals, with only small deviations (+/- 2 now and then) in the AC-3 track. > When I make a cut in the TS, DVBcut starts during export with lots of: > > Muxer problem: 00:02:47.454/02 > 00:02:46.809/79 (dts:00:02:46.809/79) > s->getbuffree():4096 > Muxer problem: 00:02:47.455/58 > 00:02:46.881/79 (dts:00:02:46.881/79) > s->getbuffree():2079 > Muxer problem: 00:02:47.532/36 > 00:02:46.977/79 (dts:00:02:46.977/79) > s->getbuffree():2368 > Muxer problem: 00:02:47.603/54 > 00:02:47.049/79 (dts:00:02:47.049/79) > s->getbuffree():2079 > > ....messages right after the cut position!

I can't reproduce that with the 2min snippet I downloaded :( I get at most one message. > But even without cutting dvdauthor reports then a few times: > > WARN: Discontinuity of 2 in audio channel 0; please remultiplex input. > WARN: Previous sector: 1.726 - 1.790 > WARN: Current sector: 1.790 - 1.822 > WARN: Audio pts for channel 0 moves backwards by 2; please remultiplex input. > WARN: Previous sector: 1.854 - 1.918 > WARN: Current sector: 1.918 - 1.950 > > Strange thing is, that the discontinuity is 2 (and not just 1 as usual)!?! And it's in the AC-3 audio track this time. So far dvbcut only detects and corrects PTS errors in the *video* stream. It doesn't even look at audio PTS when indexing. > Unfortunately the 15min recording is not very suitable to detect sync-losses, > since there are not very much dialogs... and also the 2min snippet showed no > sync-loss, whereas the same scene in the full stream (WITH a view cuts!) > showed some. Maybe the problem is somewhere else in the stream. Or there are lots of small errors that accumulate. Do the sync errors go away after a cut point? Or do they get worse and worse until the end of the movie? > Vamps always has freezes... also in an uncutted (but with DVBcut exported) > video... Did you try to play the DVD on your computer, e.g. with xine?
