When I use Nero7 ultra edition to burn video from .avi to dvd the resulting dvd sound becomes more and more unsynchronized with the video as it plays. The original .avi file is completly fine. Any help would be appreciated.
You should have read the forum rules about double posting like this as it's frowned upon.
And use originals, so there would be no need for converting avi>dvd."burning avi to dvd" is impossible.
I solve the problem exporting the avi file to another avi file first. in the nero 7 exporting options, once you do that you can burn the dvd and should not have the audio unsynchronized.
