[mythtv-users] Excessively high CPU usage

[Sasha Z]

I've got about 22% CPU idle using the following hardware:

Athlon XP 1700+
512MB DDR
40GB Barracuda IV
PVR 250 MCE
GF4 MX440

Using Arch linux, and mostly the newest software, except the older
6111 nvidia drivers. Anyway, my CPU usage used to be much lower, with
about 75% idle. I'm using kernel deint and denoise3d, no xvmc or other
funny options. I am using opengl vsync.

Any thoughts on this?
