I have a Toshiba hd-dvd which normally plays dvd's just fine. When a dvd starts, it says that it's changing to the resolution the dvd is set up for. Well I got an old dvd for the tv movie The Stand (early 90's maybe?) and the picture is very choppy. Any idea how I should try and change anything on the setup of the hd-dvd player? I can't remember the exact details on all this 24hz, 30 fps, 60 fps, etc stuff.
