I have a DVD that I burnt from an image file. The dvd plays perfect as an image file, the burnt dvd-r plays excellent in my computer, the problem is the burnt dvd-r won't play in my standalone player. I was thinking maybe its a region code or it is not recorded in NTSC? How would I find the dvd's region code and the recorded color system? Any other suggestions as to what it might be? Thankyou!
