Except in this case the video had been on several other web sites for
years, and I asked if I could mirror the video from one of those web sites
(which no longer exists and why I asked to mirror the video), and they responded
it was OK. This is different than using some file sharing or torrent program to
download music that was never intended to publicy available in the first place.

Everyone involved in the original discussion, except for RSC, agreed that
that no one was going to file an infrignement claim or ask for removal this
particula video, since the video was old (at least 3 years at the time),
and on several fan oriented web sites.

Note that there's no requirement for pre-emptive prevention of such
videos being posted, as demonstated by youtube. They aren't held responsible
for uploaded content until contacted by an entity claiming to own the
rights to the video. At this point, they are given reasonable time to
contact the original uploader to see if he contests the copyright claim.
The original uploader is given the chance to dispute the claim, in which
case the video remains, or the uploader can delete the video. If the uploader
doesn't respond, the video is removed.

If repeated infringements occur, the copyright owner will ask youtube to
pre-emptively remove uploads with certain key words in the desciptions.
Youtube has no ability to screen the actual video content with some sort
of AI viewer. The same video with out the key words will probably never
get detected (but never seen by many either).
