[mythtv-users] CPU usage spikes in liveTV on EPIA M10000

[Paul W. Smith]

I'm getting occasional CPU usage spikes (to 96%) when watching live TV in 
Mythfrontend on an EPIA M10000-based system.  When this occurs, I get 
stuttering video/audio.  

Specs are as follows:  MythTV .14, M10000 MB, 256MB Ram, 7200RPM 80GB Seagate 
Drive, Gentoo-based, open source CLE266 driver, XFree-EPIA, Kernel-2.4-EPIA, 
PVR250 w/ ivtv driver.  The input is from DirecTV DSS, if that matters...

It doesn't happen all the time, but when it does (I'd say every 5-10 minutes), 
it usually happens multiple times in succession.  I'm running all of the 
modules except Mythweb, and I've optimized the system by turning off 
unnecessary processes.  When it is not spiking, I usually see around 40%-60% 
Mythfrontend CPU utilization when watching live TV.  

Has anyone else with a similar setup experienced this?  Are there other things 
I can check or things I can do to tweak the system?

TIA
