Watching Live TV is really watching a recording. If watching a  
recording is OK the additional load of making the recording while  
watching it should not be too much, assuming hardware encoding.

You might be having problems with disk transfer speed which may be  
related to PCI latency, look on the WiKi for info on how to possibly  
get better disk performance by tweaking that a bit. Also check the  
obvious stuff like making sure DMA is enabled on your disk(s).

If the problem is really CPU load not de-interlacing might help, but  
not if the trouble is actually disk transfer rate.

Try playing back the recording made while watching liveTV with your  
MVP to see if the problem is with the recording or the playback.
