The 'fold-over' at the top of the video?


I don't understand what you mean by "fold-over".


I didn't notice it at first as I was listening to your 'static' but
look at the top of the image. The first few lines coming and going
might actually be from an adjacent RF track from wear out / poor
alignment or may be the Drop Out Corrector (DOC) repeating the last
available material. If you don't know what that means you should look
up how a video tape machine works with the rotating head. I promise
that once you understand a format, they all work the same, even the
digital and HD machines. The details are different but the concepts of
RF, tracks, servos, control tracks and Time Base Correction is common
to ALL video tape machines. I've been repairing broadcast machines 30
years.
