man nice
man renice

Basically set the priority to the lowest:

IIRC something like

renice 20 f at h

should do the trick.  I do the same thing; I have a huge ffmpeg job that
runs for about 10 minutes, hammering the drives and the CPU.  It caused
all sorts of problems with myth until I re-niced it to the lowest level
possible.
