I'm having the same problem. But at most I've been using 150 images per slide show. The program either stops half way through, display's a partial image or gives an error message saying "jpeg invalid". I'm new to this program. I haven't put music to any of my slides yet, so I know that can't be it. I was wondering if I had to many images on the slide? I am also burning them onto CD's. Should I be using something else. My main use for them is for proofing professional photography images. Any help you can give would be greatly appreciated. I'm so anxious to start using my slide show productions.
