I uploaded blackmagic.codecs.conf, which has the qtv210 entry near the 
top of the file. The rest of the file is the codecs.conf that comes with 
the current revision (SVN r26003).

I also uploaded BMDCodecLib.dll, which is the free DLL embedded in the 
Windows XP MSI file that one would download from Decklink. I presume 
that future versions Decklink makes available would work similarly and 
that one would only have to overwrite the one I uploaded with a newer 
version.
