VHS to mpg - big sync problem

[Conrad_71]

Hello everybody,

I'm kindly asking you for help by the following problem: I have captured a whole VHS cassette - using an ADS Tech device with the delivered software - on my hard disk. The capture was made directly in mpg format, resulting in a 14,4Gb movie (it's a whole wedding ceremony on it). I can play the mpg file without any problem directly from the hard disk, without sync problems, but as soon as I use an authoring software (for ex. TMPGEnc DVD Author 1.6) to prepare it for burning on a dvd, after about 20 min. I observe that the sound comes a few seconds later than the image and it will be worse as I'm playing further!!! I have tried also other authoring softwares, with the same bad results !
I have to say that the VHS-movie is made from many single sequences (it is of course not a continously movie) - could this be a reason why the syncronisation will be lost?
Please help me with an advice, I'm really out of ideas...

Thank you very much in advance.

Try run through the mpg in Videoredo using the quickstream fix. Then author it. It usually fix audio sync issues.
