[mythtv-users] Anyone successfully displaying 720p or above on a Pundit?

I have a Pundit (the one with Sis 650, not the -R) connected to a DCT
6200 cable box (Comcast in Philly) via firewire.  I installed Myth
following Jarod's guide using FC3, latest atrpms packages.  I have no
trouble displaying the NTSC-size channels coming in over the firewire,
but I have problems trying to display 1280X720 or 1920X1080 HD
channels, so I'm wondering if anyone else has run into this on a
Pundit and got past the problem.

If I use test-mpeg2 to capture some video to a file and then 'mplayer
-vo xv" to play it back, no problem.  And if I have Myth configured to
use libmpeg2, the video looks all screwed up, but Myth still
functions.  Also, in the small preview window in the Myth playback
screen, the video looks fine.  However when I try to play it back,
Myth gets a seg fault.  mplayer plays the same .nuv file ok
(horizontal position is off though).

Note that the problems I'm having are for network HD channels only - I
haven't been able to display DiscoveryHD or InHD at all, either in
Myth or mplayer.  I saw in the archives someone mentioned running
Discovery through mencoder, but I haven't tried that yet.  First I
want to solve the network show HD problem.

The video clip can be played in mplayer, so the clip is ok and the
horsepower is there.  Lots of people are using Myth for HD playback,
so I know it's not broken.  So I figure maybe it's some combination of
how Myth (executables from the mythtv-suite in atrpms) is compiled,
and my particular hardware.  I've attached the output from the
mythfrontend log.

I figured I'd ask if anyone with a Pundit is doing this successfully
before I start recompiling with other options/debug info.
