Tom I figured it out ,I had a few different .exe files and some .pte files all saved in the same folder from playing around with the program and when i clicked on one of the .pte files to create a dvd I guess it was somehow using all its memory to read all of the shows at once ---------- don,t know how or why but i remembered having the same kind of issue with my other slideshow program Xatshow. So I,ve had to trick my computer ----I put the .pte file I want to create a dvd with in it's own seperate folder and voila everything works . Thanks for your interest hopefully it keeps on working Simon
