DVDLab Pro - Audio-Video-Sync Problems.

[Rob Mynott]

Right, here's my problem.

I have compiled and edited my own documentary, and am now using DVDLab Pro to author the DVD. In my video stream I have:

1 x M2V File
1 x AC3 - 2.0 Stereo audio
1 x AC3 - 5.1 Surround Mix
1 x DTS - 5.1 Surround mix.

All is well with the DVD, until I author it. The intro screen works fine, as do the motion menus. However, as soon as the main movie begins to play, the video-audio-sync goes completely to pot. Sometimes the video plays too fast, sometimes too slow. This changes, but is never correct, when I switch between audio streams.

Does anyone know what the problem is? Could it be that the combined bi-rate of the video (8MB p/s) and the three ausio tracks is too much for my player and / or PC to handle?

Any advice would be much appreciated.

The video and audio bitrate combined probably exceed DVD spec.
Why 3 audio tracks? Different languages, or you just want viewers to be able to choose?
How much of your audience will actually use DTS?
Is it worth having that track?
How did you get the audio tracks? What did you use to generate the m2v, and the audio?
Are they all at 48khz?

What are the bitrates for each of the audio tracks, and what is the maximum bitrate used by the video ?

I've sloved the problem by lowering the bitrate of the video.

The video was encoded by Avid, and then re-encoded by TMPGEnc. The 2 AC3 tracks were encoded using Steinberg Nuendo with Dolby Plug In, and DTS was encoded using Surcode DTS encoder.

Thanks for your help.
