Audio Synch

This is really weird. I am trying to burn one movie, hour and a half long, using nero express. All seems fine when I first start burning. THe first burn, i take out the DVD, and there is absolutely nothing on it. It is still blank. So I try again. THe second time I burned it, it came out where the audio was 30 seconds and gaining faster than the video, and when the audio ended, so did the entire movie, so in the end the audio played but the video was about 15 minutes behind and the ending was not on the disk at all. Any help?

Nope, that is impossible.
Burn with verify, then you will see that content were burnt onto the media.
