I'm still kinda new at this and when i used nero to code and burn a movie in an mp4 format and burned it to dvd there is a 1/4 inch bar at the bottom of the movie. not sure if i caused this cuz during the setup process it asked me if i wanted to keep it in PAL format cuz most of the file was in that format or change it to NTSC. i chose to leave it in PAL. Any help with this would be GREATLY appreciated its annoying to have a great copy except for the bar.
