I tried to convert the star wars movie to mpg using ulead video studio 5.0 When I tried to burn it onto a cdrw using roxio cd creator 5.0, it only gave me the option to record in PAL format. When I tried to play it on my Sony DVP-NS400D, the movie should stop after the first 57 seconds. Is the problem that I an trying to play a PAL format instead of NTSC?
