ok let me get this straight, you or she probably created a file with photo movie maker to creat this pmm file right?
so what she has to do is...export the file out as a .mpg file or .avi file instead of the default program file.
like when you use photoshop, you don't save the file as .pdt, but instead as a .jpeg or .gif unless you intend to come back and change your work
oh course your media player or vcd player won't open it, it's a file that needs the program itself to open. it's not a file type that would burn as a vcd
what do you mean a photomovie software? isn't that what she has already?
to make things clear i think you need to tell us in the first place why she is using photomoviemaker.
