    What a great article!

    I always thought the annoying dimming was some kind of copy protection scheme, like the old Macrovision from back in the days of VHS.

      Wow, that sent me down a rabbit hole of searching. I am old enough to have messed around with lots of VHS tapes in my day, but I was still too young to know what was going wrong with the picture. Reading how Macrovision screwed up the picture through desyncing the scanning explains why some of the “non-authentic” tapes I got never played right for me.
