they r probably 16mm film, but in negative form. this means all the black images are white and all white images are black. they probably used these negatives to make contact 16mm positive prints. if u tried to project them u will see a reverse image. there are film telecines that can reverse the images or maybe it could be reversed if u fed it into an expensive computer system but would it be worth all the trouble just to view an episode with original commercials? its still a nice collectors item.
