Nero Express3 sticking problem



Hi everyone, hope you can help.
I’m trying to burn Avi’s and mpegs to dvd-r using Nero Express 3. It’s worked perfectly well for some time but recently, when it decides it does want to copy, the end results have extremely annoying playback problems - namely sticking and jumping throughout the first 2-3 minutes.

I’ve tried missing out the menu making stage in case that was confusing the issue - didn’t help. Experimented with burning speeds too - that hasn’t helped either.
Can anyone recommend anything that might help? It so very nearly works perfectly! The sticking/jumping thing happens both on PC playback and on standalone dvd player.

Failing that, what programmes should I be looking for to burn avis and mpegs to dvd that might be better?

Thanks, I really appreciate your help,
