I could be wrong about the stream format, but none of the "usual"
tools work on these - FlashGot, Pocket, and so on.  Youtube-dl is
inapplicable since ithese videos are not on YouTube (and I use
youtube-dl all the time with very little trouble beyond updating when
I missed a change).

I mentioned jwplayer because these seem to be the ones that resist
downloading via FlashGot, etc.

Thanks, though.  :-)
