I am having a problem with Nero Vision 4. When I burn the movie to disc, the picture gets a little jittery at several chapter marks. This jitter lasts anywhere from a split second to about 5 seconds. It seems to happen whether I create chapters manually, or let Nero automatically detect them. (Although it is worse if I create the chapters manually). I suppose I could just not create chapters, but I'm hoping someone has a better solution.
