Thanks for the extensive explanation, and as someone
who's helped with
Wikimania video in the past, I absolutely feel your pain and commend you
for doing what you have so far.
Downloading from YouTube violates their TOS, though you'll notice people
do it all the time.
I've uploaded thousands of YouTube videos to
archive.org, I can do these
too with no problem.
