The wiki page just says "compressed to 200kbps", which is not nearly enough
information.  I was going to just update that in the wiki, but then ended
up replacing a bunch of the earlier text.

 Before, it didn't even mention that modern codecs have built-in
deblocking, and usually don't look better when you PP.  Anyway, I rewrote a
lot of stuff, and I think it's a lot more informative now.
