[mythtv-users] X high cpu usage

hi jim,

i too am in the same boat as you. i have a p4 2.4, 1gb ram, dvb-t card,
gentoo-2.6.16 kernel, mythtv-0.20, nvidia 6200, latest nvidia drivers, no

watching livetv i get cpu usage being very high (attributed to X), hence i
get the stuttering and the same errors as u. if i pause, then unpause during
live-tv it does fix the stuttering but the cpu is at 98-100%.

a temporary fix i have is to renice the X process by -5 which has a dramatic
effect on cpu...ie bringing it down to 30-40%

however, one side affect of this is that it tends to cause problems when i
try to seek, ff or rwd when watching a video.

in 0.19 i dont recall having this problem. are the devs aware of this? if
so, are they working on a fix?
