It's expected when I've got 2 transcode jobs running. They are nice'd  
to use up whatever CPU is left over after doing all the other  
important stuff.

This box is a single core AMD 64 3800+. My dual-core AMD 64 4400+ did  
the same thing when that was the master backend. It would use up both  
cores for transcode jobs, but I never had even the slightest delay in  
doing anything else on the box.
