No problem on the delayed response, I was following
the issues on the mythtv-dev list that you were
seeing. I'm running with 2.6.8-521.

I think that I'm using it... If I run glxinfo, it
informs me that direct rendering is enabled, and
glxgears is returning about 500 frames per second.

Well, I'm not sure if the deint is actually doing
anything or not... But I'm pretty sure that I'm
actually using XvMC, because the OSD is black and
white, and the options are checked off in the GUI. I
will be doing more looking into this over the weekend.

Hmmm... Perhaps the difference is that I was doing
this in LiveTV mode... For the life of me, I couldn't
get anything working cleanly out of the GeForce 440MX,
or an ATI, or a Matrox for that matter. They all
showed issues with the ticker. It seems that if the
ticker is smooth, then the rest of the picture is
mostly smooth, which is kind of important for watching
any kind of sports. Especially fast motion, like
wrestling (which isn't a sport, and it's value is
debatable - but I was able to watch WWE Raw last night
on the Epia, and it looked great - lots of fast

I think that's the route I'm going to go with mine.
Get a 10GB (or smaller) 2.5" laptop drive, just enough
to boot the system and give it some swap space (if
necessary), and fetch the recordings and everything
else over the network. They'll come from my dedicated
xmame machine. :)

The stutter happens off and on with mine, it's
difficult to predict when it would happen. In fact,
it's the same thing that happens on my PVR-350 as
