Okay, so basically, whenever I try to burn a dvd from my computer it doesn't work. I have tried 2 diff. ways, those being: I tried using "make your own dvd video" and I also tried "copy dvd video movies to cd" and the dvd either doesnt recognize the file, or it just stops recording half way through. they only file i can find to convert to in nero is mpeg-4 and apparently thats not working. help if possible, thanks.
