Tilt.  Something wrong here.

This is going to take a fair amount of time to run, and eat up a lot of 
processor while doing it.  On an underpowered system, this will very 
likely cause sluggish playback.

That amount of CPU usage seems about right for that processor doing 
playback of HD MPEG2, but the Xorg usage is troubling.  That sounds like 
improperly configured graphics drivers, or maybe you're using OpenGL 
through MESA.
