I've wondered about the various offerings as well. From early reports, it looks 
like the G210 cards are not quite powerful/fast enough for the most 
demanding codecs, and the GT220 cards barely make it over the line, but I 
don't expect there are very many of these cards in the hands of MythTV uses 
yet.

This card:

pushes the core clock to 720 MHz, shader to 1566 MHz and the memory to 
1600MHz. The more common clock numbers seem to be 625-650, 1360-ish, 
and either 800 or 1000-1580 MHz. I wonder which numbers are important for 
MythTV?

This card is not fanless, but the fan is huge, slow and (suposedly) quiet, and 
you might be able to use an aftermarket passive cooler on it. Some of the 
reviews say it overheats, but it would appear that the reason is lack of fan 
control in the Windows drivers.
