I'm going to go through the official support channels with this too, but wanted to poll the thoughts of the forum experts.
I regularly make DVDs for clients, but one of them seems to be plagued with playback sync. issues, issues that I really can't see or nail down on my end.
So far, the source video for his discs has been provided as MPEG, either off-air or on DVD from the TV companies involved. The audio has been either stereo 48kHz PCM or two-channel Dolby Digital at 256kb/s and the video MPEG-2 at 704×576 or 720×576 PAL.
The footage is dropped onto the Vegas timeline or split in the trimmer. Most of the time the edits are really simple, just straight cuts and the odd fade, but there have been projects with multiple video tracks and cut/pan events. I tend to leave a second or two of blank space at the start of the timeline and render with it included so that the footage has shoulders.
It's rendered out of Vegas using the MainConcept MPEG-2 encoder at various variable data rates in the DVDA profile, and as 192kb/s Dolby Digital.
Those files are passed to DVD-Architect and the DVD created. The assembled files are then burnt using CopyToDVD and Plextor drives onto Panasonic or Verbatim blanks.
I then check the finished product on a number of DVD players, Panasonic DVD recorders (two different ones) a Pioneer and a Meridian, I even play them back using the software players on a couple of PCs. They look fine.
However, my client often mentions that they're out of sync, not just by a little bit, but by an amount that makes them unwatchable. He's using the software player in a Dell and a Sony stand-alone player.
We've made a lot of DVDs over the years and they've gone out to hundreds of people. So far nobody else has complained about sync. issues, but this is an important client and he's understandably worried about giving discs to others to view.
Incidentally, we've also tried authoring the discs in DVDLab Pro and our client still says some of them are out of sync. We've even tried reducing the data rate of the MPEG files to no avail.
I wondered where the forum experts would start troubleshooting? Any ideas for an alternative work-flow? I'm wondering if converting the original MPEG-2 footage to AVI intermediates outside of Vegas as the first step would help? If so, what software would be suggested?
