My Matrox G550 is dual headed and has one DVI and one VGA connector.

My Intel Pentium 2.8 GHz HT CPU can decode, scale and deinterlace a 1920x1088 
HDTV 1080i stream (Euro1080) to a size of 960x544 with a maximum CPU load of 
70 % (most of the time about 60 %). Kernel 2.6.0 performs even better, due to 
less peak loads on the two virtual processors. So I think, native HDTV 720p 
mode should be possible with such a machine, using my vdr-xine plugin with 
xine / fbxine.

Bye.
