Thank you for your suggestions. I can now create an image (ISO) and/or burn the DVD from the project. I have a main menu, 6 submenus deep. I can run each of the 23 menu options (slideshow / movies) with no problems.The total project is less than 4Gig (per Roxio). I can burn the DVD, either from the ISO or direct from the saved project. However, at the same spot it stops recording the images (photos) and I get a black screen. It continues to record the timeline until the end of the project. I think it is a virtual memory issue!! Any suggestions.???
