I still have the card.  It's running in my Wife's computer, working 
beautifully with the legacy proprietary driver, still using less CPU to 
play back HD recordings than the new system.  I tried to buy a new one 
for my new FE/BE/main Myth HDPC but couldn't find the 5200 in a PCIE 
(only AGP).  I tried the oldest PCIE I could find (think it was a 5500) 
but it didn't support the overlay (wouldn't run on the legacy driver).

So, I take it no one with PCIE motherboards have picture controls 
working?  That just seems unlikely.  Anyone?
