I had a silent Super 8 camera and I did try to film off the TV, but it came out blurry, over-exposed and unwatchable with scan lines, etc. It was a "Family Feud" opening from 77, so it's nothing rare. The film cartridges had about 5 minutes of film (50 feet), so you'd have to have quite a few cartridges if you wanted to get a whole show.
