[mythtv-users] Mythfrontend idle cpu consumption help

[Steve Malenfant]

I have Fedora Core 12 and seeing the mythfrontend started idle 7% usage.

16963 steve     20   0  379m  83m 3896 S  7.3  9.6  62:25.79 mythfrontend

model name      : Intel(R) Core(TM)2 CPU          4300  @ 1.80GHz
stepping        : 2
cpu MHz         : 1203.000


Running the latest update from atrpms as of today. I think it is a bit silly
that CPU is used on a screen that doesn't move.
