And a small note - the “original” versions on the BluRay set are actually NOT original versions (at least in some cases), and few episodes are different from their DVD versions, but I have no clue which one is the “original”, e.g. Arena https://www.youtube.com/watch?v=cJ26yeTNvvM or By Any Other Name : https://www.youtube.com/watch?v=unxotSzrv3w
Well in the video above they mentioned that the piece of metal was in the original plate for Arena. Perhaps it was cropped out for actual broadcast, even though it was in the negative?
