After monitoring my FEs for a few days I have noticed that the CPU usage 
jumps from 2-3% to 30-60% when mythfrontend is in standby mode and the 
BE is recording. So far it appears the the CPU usage returns to normal 
when the BE finishes recording. It may be that the mythfrontend gets 
stuck at a high CPU usage because of this situation but I haven't seen 
that yet.
