I'm using Nero 7 to burn DVD's of short films one of my friends produce. Usually 30mins to 60 mins long in MPEG 3 format.

The files burn ok using " Make your own DVD Video", as video clips, but what I'm finding is that 10 mins into the recording , the audio starts to get out of sync with the video images.
I've re-installed Nero, and actually re-installed Windows XP after I was adivised this would help, but it still happens. Any ideas?
