DVD Authoring, audio delay?

[SajBot]

Hello!

I got one problem that I hope you guys can help me out with...

I use to demux the DVD's in dvddecrypter, streamprocessing
and all that...
And when I look at the .ac3 file, it says 0ms in audio delay,
so I just re-authored the DVD in DVD-Lab PRO, BUT, when I playback
the DVD it's not in sync :S

And this only happens with some DVD's, from the most of them I get the audio delay and they playback fine in sync...

Could anyone help me, how to find out the audio delay?

Thanks

Open 1 of the original VOB files with VirtualDubMpeg2. Under File Information, check the audio skew.
