The top several processes are all mythfrontend. It's using ~60-80% of
the cpu, followed by XFree86. Everything else is using 1% or less.Only
100MB of my 256MB swap is in use. It actually plays a second or two of
video, then freezes for a few seconds, then plays again for a few
seconds. This repeats as long as I let it. I'll try setting things to
480x480 and see if that helps.
