First, you should do this:
http://www.gossamer-threads.com/lists/engine?list=mythtv&do=search_results&search_forum=all&search_string=IOBOUND&search_type=AND

Here was the thread I asked the same question, and where I got the best 
answer (from Chris):

But to be honest, the only thing that worked for me was to stop any 
background CPU hogging processes going on while recording.  I was 
transcoding shows, I wrote a script which does a killall -STOP transcode 
at 7:59pm and killall -CONT transcode at 11:00pm (my main hours of 
recording) so I can pause any transcoding I'm doing during prime-time.

Good Luck
