Another scene in the same Episode is when they pan away from the vagrant with the chess piece in his mouth pointing to the chess board, when they pan away from the vagrant, on the left side of the screen, you can see him blink.
I dumped the VHS tapes a while back but would love if someone who has it could check this out for me.
I think either they screwed up on the framing of those scenes or they have always been there and only now in the clarity of the picture are they being highlighted.
