[mythtv-users] Problems running Myth - segfault starting liveTV

I've been working on a MythTV box for a few months now, and it's been
one trouble after another.
Word of caution: Pundit-R's don't seem to like SATA HDD and PATA DVD
I've put in a Hauppauge PVR-250 and a 160GB PATA drive along with the
The system is running Gentoo 2005.1
So far, so good, I can watch DVDs through mplayer
I installed the Hauppauge card, and had problems getting it to tune.
Seems that the tuner module does not load with the correct tuner
parameter. On boot I have to manually unload that module with an
rmmod, and reload it with a "modprobe tuner type=39". Then the card
will tune to NSTC cable (using mplayer & ptune-ui to test)
Started up Myth for the first time. Backend runs OK, frontend starts
OK. Try to choose Live TV, and the screen goes black for about 5 sec,
then returns to X (using evilWM) with a "segmentation fault" error.
No other information is provided.
I've rebuilt Myth from source, and build using the --debug option, but
I can't seem to get mythfrontend to start from a virtual console and
display on the local X. it tells me no X server is available (yes, X
is running, and the DISPLAY variable is set). Running mythfrontend in
gdb locally ends up locking the display when it segfaults. Ctl-C, etc
does not get me back to the console to view the GDB output (only
solution is killing the X server).
So, I turned on verbose logging. Just before it segfaults, the
logfile shows myth looking for /dev/nvidia0 Which doesn't exist on
my pundit's ATI board.
Following this recent thread:
http://www.gossamer-threads.com/lists/mythtv/users/144660 has not
proved helpful as the instructions to disable XvMC (settings -> next
-> next, etc). don't jive with myth 0.18.1
The .configure output when building myth shows no XvMC and no OpenGL
support, so, wtf?
Bottom line: Why is myth looking for /dev/nvidia0 when it shouldn't
be?, how do I stop that?, and why will there be no broadcast HDTV in
my area until fall 2006?
Thanks for anyone's help. I can't imagine that pundit-R + pvr250 +
gentoo is a strange combination, so odds are SOMEONE has fought with
