I use the latest release of Nero to burn all my DVD’s. I find that I usually get this same problem. When I watch the .avi file on my PC it’ll be OK, but after burning it…somtimes, partway through the DVD my audio will start coming out of synch…or the video will start getting choppy. Yet, as I say…the .AVI itself is fine cause I can watch it on my PC and it’s perfect. Any help would be appreciated.
