OK, finally had the time to do this.  The onboard video is GeForce4 MX
NV18.  I boosted the box's system RAM to 512MB and give the video card a
64MB framebuffer.  I also verified that xv and xvmc are enabled on the
server side by using xdpyinfo.  I also verified that it is using AGP.
I'm running at 960x540p using your modeline.

Now the hdtv clip is quite choppy.  It works OK for the first 1-3
seconds, then gets all choppy.  At least I have a picture :-)  The sound
gets choppy, too, BTW.

But I'm at a loss what to do next.  If you have any other suggestions
for me, I'd appreciate them :-)

I thought of XvMC, but I can't:

1. Figure out whether or not it's already enabled;

2. Figure out how to enable it.

Just to recap, I'm using the MythTV .debs on this Athlon XP 3200+
system, 2.6.7 kernel.

Thanks again!
