[mythtv-users] XFree86 CPU utilization

[Joe Yang]

I think the on-board S3 video chip is PCI and the nVidia TNT2 Riva is
AGP. Basically, I got same problem on PCI and AGP interfaces. It looks 
like Geforce 4 MX video card has the same problem. I don't even sure
this is video card problem or not. No clue so far.
