I was addressing the source of the problem, not the question it led  
to. Lowering CPU requirements. I am currently running VDPAU code on my  
production system and I'm quite happy with it, so calling it "very  
preliminary  -- basically conceptual" is not accurate. As soon at the  
OSD is working correctly, it meets all my requirements and I would  
consider it done.

Back to the topic at hand - lowering CPU requirements for h.264  
content. Right now, the answer is VDPAU. I would say Windows support  
in MythTV is even more preliminary (since I often see messages about  
how broken it is - I don't know for sure since I don't use it). You  
would certainly wait longer for PureVideo Windows support in MythTV  
than VDPAU support in linux - again - available today.
