Probably 100's of things could be causing it, if you could list far more detail then we may be able to help.
Start at the very beginning and work your way through to the end production of the dvd and list each step adn setting you made. Too much info is preferable to to littel, so include how you got the video in the first place, like from digital camcorder connected by firewire, chose capture, used dv-avi file setting.............
Also tell us when it goes out of sync, just on the dvd? Have you checked before this stage? Is anything else used in the movie, stills, music etc etc....

Over to you.

I obtained the video from video tape of television broadcasts. copied them to the hard drive using DVC150 and moviestar, which was created for the DVC150. after capture, I used Ulead DVD Moviefactory 3.While using Moviefactory, I am able to check video/audio synchronization and all seems to work very well, it is after the movie is rendered, and saved on the hard drive as a DVD that I can play the dvd on the computer it was created on. The movie starts with no problem in the synchronization, but after a few minutes (15- 20 ), the sound and video is out of sync and grows worse the longerthe video is played

It's captured as an mepg. In movie factory are you when "rendering" remaking the mpegs for the dvd?

? what do you mean remaking the MPEG's

MPEGs are not designed to be edited except by a specialist MPEG editor such as womble or videoredo. You may be able to correct the MPEG video you have edited by passing it through one of the two above programs then running it through Movie Factory to create your DVD.

The video has something called PTS - program time stamps, these keep the video and audio in synch but are discarded when converting to VOB files. This is why it appears in synch when viewed as an MPEG and out of synch when converted to VOB.

How do I create VOB files for DVD, without losing the timestamps. Should't Ulead do this without losing the timestamps???

VOB's don't have time stamps, that's why you end up with out of synch videos when they become DVD's even though they were in synch beforehand.

You need to correct any synchronisation flaws before you make the DVD.
You can often do this by running it through Womble or VideoReDo.

Best is to avoid the problem in the first place. If you can work with AVI files you shouldn't get a problem. If you must use MPEGs then keep editing to the minimum, avoid transitions - this is where two pieces of film overlap each other and are the most likely point where out of synch issues develop or use a specialist MPEG edit like Womble.

If you use Womble think of it as a whittled down version of Video Studio, does a similar task but not as powerful

sjj1805, thanks. In the last year or so that I've been doing this and have had the sync problem, that is the best explanation I've heard. It sounds like its common and going to happen with the mpeg files then? (Wonder why Ulead couldn't/can't have told us this???)
All of my probems are from cutting and trimmiing vhs tapes that I have transferred using Hauppauge USB II. That of course does it in MPEG. Do you have any famous last words for doing it like this (without having to buy another program?)
Thanks again in advance
