I got the Blackmagic codec for XP to work on Fedora 6. After installing 
the MSI file on a Windows box, I transferred the BMDCodecLib.dll file to 
my F6 system and installed the DLL file into /usr/local/lib/codecs with 
the others. I added the following to codecs.conf:

    videocodec qtv210
    info "Win32/QuickTime Blackmagic 10Bit"
    status working
    fourcc v210
    driver vfw
    dll "BMDCodecLib.dll"
    out BGR32

Setting the driver to qtvideo fails because qtvideo appears to only 
check for the various Quicktime DLLs, typically using the qtx suffix. 
But, the vfw driver worked. Maybe one of the developers will add this 
entry to the default codecs.conf.
