FxFotoMovie.mpg files

Hi, I have used FxFototo make a slideshow that converts to a MPRG file, but when I try to burn it using MemoriesonTV it will not open the files.
I Have WinXP home edition , does anyone have an idea of how I could get the .mpg files to open. I have contacted FxFoto but the replies can take 2 to 3 days and I really need to know this toaday. Thanks Mac
