The landing was broadcast live around the world. My question is,
aren't there many "original" tapes that various news and other
organizations would have in their possesion that would make this point
moot. Is is just a question of "NASA's" copy gone south? Does it make
a difference?..........Doc

It makes a lot of difference. NASA's originals are much higher quality than
what was broadcast live, due to the low-tech NTSC conversion method used
(literally, point a TV camera at a monitor playing the original).

The following pages, from Australian radio telescopes involved in
tracking Apollo, provide an indication of the considerable degradation
that resulted from the scan conversion process:

Hopefully, the raw data tapes will be found - in readable condition.
