See, especially the "I'm not aware" part of Daniel's response.  I have a
GF7800GTX, but I haven't yet had time to upgrade since the mythtv-vid
merge (been on the road).  I should be doing an upgrade in the next
couple of days.  When I do, I'll see how mine handles it (I don't expect
it to be able to do 1080i playback--and, especially not at 1.5x :).
