I have taken a PowerPoint presentation, made it into a png file, and using those slides and some short mpeg-2 video clips, have used Windows Movie Maker to make a video. I've saved it as a wmv file and then imported it into NeroVision Express 2E to make chapters, menus, etc and burn it to DVD+R. So far so good. It all plays perfectly on my DVD player except when I get to one of the video clips in the movie: two minutes into the video clip, the video clip starts to freeze, jump, and skip for a minute or so, then returns to normal. Any ideas on what is going on, or suggestions to fix it? I've tried burning at 8x and 4x to see if that helps, but it doesn't. Is it the wmv format causing this hiccup? I'm not sure what to do... Thanks!
