Tom, you missed a trick. You should have ended with the scrolling white noise revealing an old episode of 'Things You Might Not Know' that was taped over.,(reply>), VHS and Betamax were released 1975 if I recall correctly.  Umatic in 1970.   Many “lost” Doctor Who episodes were discovered on these formats.  Typically as reruns (not original broadcast)<br><br>.,(reply>), Except it would have to have been that old episode that was taped over this one, because if this one was taped over the old one, then there would just be blank afterwards and then the taped over section, where the tape had already been erased ahead of the recording head and would not be recorded over because recording had stopped, then after the erased section is the old recording.<br><br>If what came on afterwards had been recorded over this episode, then you would get the funny picture where recording had started immediately on a part of the tape that hadn't been through the erase head, until it gets to a point after a second or two where the video is being recorded on freshly erased tape.<br><br>An if you have flying erase head the you don't get any of that because the erase head is on the video drum and takes out each frame immediately before the video write head goes over.,(reply>), @Joseph Davies Those weren't broadcast in the era or VHS recorders in case you didn't know.,(reply>), I taped over my kids copy of  "Mickey's Christmas Carol" with an episode of "Junkyard Wars".<br>    Never heard the end of it.,(reply>), ... turns into parents wedding video....
