bluedan is an unknown quantity at this point

Hm, I'm not that kind of hardware expert, this is still rough stuff to me, also...
but I doubt that it's your "Mystique" to perform YUV->RGB colorspace conversion (apart from the signal transmitted to monitor being of course RGB!), because this ought to be the job of the software department.
The graphic card is only being told by Direct Show to build display matrix in certain color format that it's capable of .
Normally Direct Show checks if YUY2 or YV12 overlay can be initialized, if the graphic reports back an error (for mystical reasons ?!) it forces RGB overlay. And, AFAIK, this also fails, it uses a different buffering technique to provide image data (=no overlay acceleration), i.e. slow and slower.
Of course the non-consistent window garbage is strange. Maybe the screen refresh is not synchronized with this buffering method (if it's valid info), who knows? Not me.
Keep forum organized and use the search button !! :o
