[mythtv-users] PUNDIT High-CPU watching TV - Fixed

Just for reference, I fixed the high-CPU problem; or should I say Thomas
Winischhofer did!

Enabling MTRR in the kernel took the CPU used by XFree86 down from 50% to
less than 1% whilst watching recordings.

Hmm, you see the filters in the mythfrontend cpu figures. The XFree cpu
use suggests that your Xserver does scale in software not hardware. Look
at the capabilities of your server. Or try grabbing in exactly the same
resolution as your X resolution.
