Maybe about 5 years ago at the museum of broadcasting in NY I saw them show a variety show (Carol Burnett?) and was amazed at how poor it looked....color bleeding everywhere, smears akimbo, camera burns from bright objects etc....looked like it was from the 60's and not the 70's. Not sure all of this could be attributed by it being an umpteenth generation copy. I don't recall seeing such poor visuals when the show was first on the air.
