Re. #144 above. Its most likely originated on helical-scan, you can see video-head switching at the bottom of frame. A horizontal disturbance caused by the head-switching taking place in active video time. In broadcast quality machines, this was done in the vertical-interval, but needed more circuitry.
This site covers helical-scan nicely,

Section 2.4 has a bit on head-switching. If you ever saw VHS on an under-scanned monitor, you would see that effect at the bottom of frame.
The pictures are interesting, nearly mono-chrome, and burnt out. However the camera work is good, and no wobbles. It has some 16mm material, so its been post produced. I'm guessing its gone through a lot of copies to get onto youtube, and it probably cost a bit at the time to make.
We are going to see a lot of this in the future as production companies cease trading, and materials provenance is lost. There is probably some person on the planet who knows everything about that programme, small chance of finding him or her.
