Yes, I should have mentioned in my original post. While watching a movie, the
load average is typically 1.0 (for dual core AMD64). %CPU for mythfrontend.re
varies between 10-50%. There is plenty of free RAM as well. %wa is between
5-10%. I am running a dedicated frontend so I would expect that resources
wouldn't be a problem.

I am playing DVD's directly from the disc. MPlayer works without stuttering,
but I could try ripping to ISO if you think that would be useful.
