[mythtv-users] Frontend no longer displays HD?!

[Rich West]

I upgraded two of my three frontend (Fedora 7 based + ATrpms) systems in 
an effort to resolve some minor flaky problems, and now neither one will 
play HD content.  They play SD just fine.  The third system (still 
running an older nVidia driver) plays the HD content just fine.

All three front ends are identical except for the peripherals attached 
to them (TV, receiver).  I just didn't upgrade the packages on the one 
system because it was off.. good thing I did, I guess.

On the problem systems, mythfrontend is just hanging when attempting to 
play an HD recorded show.  Running mythfrontend -v all gives the following:

And that is where all logging stops.  The interface is unresponsive 
(even after hitting escape), the load average is way up, and the only 
way out is to kill off mythfrontend.

I'm at a bit of a lossCould this be an nVidia driver issue, or could 
something else?  I'd attempt to back down the nVidia driver, but I could 
only find the i386 drivers in the archive on nVidia's site.. I'm running 
x86_64.

Thanks!
