I'm running a similar setup (xbox/xebian 1.1.4/svn/BE with pvr350) and
getting good results although the poor thing swaps like crazy when I
switch from one thing to another (menu -> TV or video). However once
the swapper sorts things out it's great. One difference for me is that
I record at 480x480 but I don't know if that's significant.
First question ought to be what process is hogging the cpu. What does
top say?

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.<br>
