Doh!  I'm not making excuses for it...I'm just trying to help identify the
problem and offer workarounds.

On my machine, hardware acceleration affects color similarly for any of
those formats.  It doesn't on yours?  (Can you post screenshots?)

Sorry, I wasn't clear enough -- I didn't actually add a mask, but just
picked a different Transparency setting (i.e. transfer mode).

(I wish there was a Windows app that would just play a Movie's Video track
as fast as possible without dropping frames, so that we could figure out how
much this affects playback performance.)
