It's not your TV set. VCR tape playing produces video with timing defects that older TV sets were not designed for and not expected to deal with. The only video they expected to see were from broadcast TV stations, that had timing equipment with tight specs, as the FCC mandated.
Specifically, the VCR produces video that has a major timing error in the horizontal sync timing that happens in the vertical interval. This is when the VCR switches from one video tape head to the other that is mounted in the spinning drum the tape slides over when in play. Your TV is trying to quickly readjust itself to this poor horizontal sync, the result is the curving at the top of the picture. Newer TV sets were designed to be faster at readjusting themselves, but then be less noise immune and be more jittery in noisy reception.
