Well, I made the video on an apple, and then exported it using quick time player. I saved it onto a jump drive, and then burned it onto a dvd on a school computer. I then tried to play the dvd on an actual dvd player, and it said disc error, and then when I loaded it onto my dell laptop, it freezes. When using windows media player, it says it doesnt read this type of document? I dont know how to save it differently?
