I am trying to burn a movie, yes its my DVD and not copyright protected. When I put my DVD into my machine, it reads as 4.38 GB, my file is 4.35 GB - so i think I am good to go. After wasting 4 DVDs its erroring out saying I need more room. So ... I just placed a blank DVD in .. after 2 or 3 minutes it fills up with 313mb of info. What gives?
