It really depends on your encoding parameters... the 1GHz-per-encoder 
rule of thumb is most likely based on 640x480 MPEG-4 @ 3300 bps.  If 
you're doing 480x480 scaled bitrate, you can get away with less.  40% 
CPU utilization is, I suppose, feasible depending on your settings.

As far as running a simultaneous mythtranscode, unless you're running it 
manually from the CLI, Myth runs it at a nice level of 19, so it 
shouldn't impact other things happening on the box, which is indeed the 
behavior you're seeing.
