The myth box that is doing the encoding is a sempron 2400 with 512B
RAM (quite low specd).  The box doing the playing was a Celeron 1GHz,
which maxed out the CPU to play the video (I can play higher quality
divx's fine on that machine though).

Off the top of my head, my load average was about 1.80 across the
board whilst streaming.

I obviously don't want to up the CPU on that machine, but I could at a
pinch put mmore RAM in.  Do you think that would help?
