Hey Redhair... MANY THANKS ... it worked!

Been trying to do that for a few years now,

simple when you know how.

Found "Content URL" on left.

Highlighted everything between https, (including https, NOT including the ")

and the first (of 3) "mp4" that was PRECEDED by a "."

Then rightclick Open or GoTo

Then rightclick "Save As" or "Save Video As" to save the mp4 file locally.
