Live TV:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

Watching a recording:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
20152 root      15   0  326m 200m 124m S 74.6 39.9   1:53.39 mythfrontend

Anyway this system is not fast enough to scale down 1080 video and
display it at 640x480, without XvMC.  So I need to get XvMC working
with Myth.  I was impressed with how nicely it displays with xine, so
I would like to get similar performance with Myth.
