[mythtv] XvMC on GeForceFX 5800

[Daniel Thor Kristjansson]

I just got the opportunity to try playing a 1920x1080 stream on a
GeForceFX 5800. There seems to be little difference as compared to a
GeForceFX 5200. I'm using the 6111 driver for both. It seems like my
processor P4 @ 1800 Mhz w/533 Mhz memory bus & 256KB cache is the
limiting factor. I'd be interested if anyone has tried a 6600 or 6800
card, since those claim 1920x1080 will work. It looks as if the
nvidia's XvMC library is using about 50% of the available cycles, so
obviously it's doing at least part of the decoding on the CPU.
