So I was playing Marathon and I thought, Hmmm....Marathon....Boredom...LETS PLAY SERIES! So I played through a few levels then quit and saved the film, I went to open it, and nothing would work on my list of saved programs. So my question is, what should I use to open the saved film and upload it to youtube, and what do i need to change the file extension to? The file is saved as M1A1savedfilm.filA As it is my only saved film.
