Hi Greg:  Klaas may not have seen this yet, so...

I don't think you have given details of your playback system, but it 
sounds to me as if you need to go into

Frontend > Setup > Video > Playback

and do things with the Current Video Playback Profile, and perhaps the 
Advanced Playback Settings.  The deinterlacers can give high cpu loads.

'mythfrontend - v playback' is informative, as is the 'M > playback > 
playback data' display and the display tab in Information Centre > 
System Status.
