Actually I have a _very_ similar situation with Matrox G450 and an
Athlon64 2800+ on Via K8T800 Pro chipset. I use X.org, but the G450
seems to be awfully slow and I can't even display 720p properly. I
always thought the problem was that the card just wasn't fast enough (I
didn't really test HDTV on my earlier system), but your experience on a
slower system shows that there must be something else going on. I use a
completely 64-bit system and I have set the Matrox X drivers to use AGP
4x, but that doesn't help much. Even mga_vid with MPlayer causes about as
high CPU usage as Xv output. This seems like some sort of hardware
incompatibility, or otherwise bad AGP support for the Via K8T800 -
Matrox Gxxx combination. I've been troubled by this for some time, so
please tell if you find any solution :)
