mythtv applications crashes X

I have a very weird behavior on my FC6-64/MythTV(ATrpms version) system.
The hw-setup is PVR-150+Hauppauge DVB-T+Nexus DVB-S with NVidia 7950GT
on an E6600 CPU.
The TV-cards work perfectly with kaffeine and mplayer, so the problem
isn't there (I think).
I've had the system working perfectly for > 2 months when it last
weekend suddenly stopped recording what it was set to record and if I
now schedule a recording via the web-interface, everything looks OK, but
it doesn't record.
If I start any myth UI application on the server (mythtv-setup,
mythfrontend, mythtv...) X crashes and the final words from the
myth-application with the switch 'mythtv-setup -v all' are
"mythtv-setup: Fatal IO error: client killed".
X's final words (/var/log/Xorg.0.log.old) are
Backtrace:
0: /usr/bin/Xorg(xf86SigHandler+0x71) [0x491a31]
1: /lib64/libc.so.6 [0x382a430210]

Fatal server error:
Caught signal 11. Server aborting

Nothing remarkable either in /var/log/messages or dmesg.
I can start mythtv-setup under vnc or nxclient without problems and the
setup looks OK, but not under the local hardware X-server.
I haven't updated or installed anything in 2 weeks (I do it manually) so
it can't be a new driver/program that's causing it.
I've backuped and re-initialized the mysql database and cold-rebooted
the machine to no avail.
Ordinary user or root doesn't matter, same behavior.

Any thoughts or similar experiences out there?

I can update my question with the statement that after upgrading to
NVidias latest driver 1.0-9755, I can again open up a myth-application
on the X display. Still a little flaky though since xine sometimes
crashes X.
The recording problem for DVB-T channels remain although solved for
analog channels since for some reason /dev/video0 and /dev/video1got
redefined.
I'm digging continuously...
The weirdest part is that everything seems to have happened almost
simultaneously 'on-the-fly', i.e. on a non-rebooted system without
anything new installed.

I would suspect hardware then. Start by looking at smart output and run
memtest and see if anything falls over.

After really dissecting the PC and trying the cards one by one, I've
concluded that you're right in that there must be a hardware issue with
the DVB-T card.
When inserted with the other TV-cards it works with kaffeine and vlc but
not mythtv, but alone in the PC it's not recognized in kaffeine (forgot
to check vlc) and any myth-application once again crashes the new X driver.
So I guess it's not broken but almost... Maybe a dried up electrolytic?
Worth trying to replace them.
Will probably still work in a windows machine for normal viewing.
The hard part now is finding a new suitable replacement card that works
under linux at least as good as this one did...

Check out this link

http://ubuntuforums.org/showthread.php?p=2422264

for a fix for the xserver-crash problem.

It looks like the NVIDIA 9755 installer doesn't quite fully install itself.

I took the following steps on a Fedora Core 6 system:

cd /usr/lib64/xorg/modules/extensions
mv -iv libglx.so libglx.so.orig
ln -s libglx.so.1.0.9755 libglx.so

Then, I stopped and restarted the xserver on login "mythtv".
Before the fix, running mythtv-setup or mythfrontend would
crash the xserver. After the fix, no more crashes.
