Using "batch" should improve the situation. It starts jobs only if the load is 
below a limit. due to the threaded nature of mythtv I get loads of about 2 
and CPU usage of 40% (P4 2.4 GHz, full PAL, bttv card). "batch" needs a load 
< 0.8 by default to run the script. As "batch" comes with "atd" it should be 
on your box.

It will not detect recordings that start during mythfilldatabase.
