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

Sun Aug 21 00:16:44 UTC 2005

I'm not real worried about the modprobing..  that's easily fixed with
a script.  I re-emerged with the -opengl  and -nvidia flags in the USE
line, but still no joy.

Here's the output from mythfrontend -v all:  (fyi - floyd is the machine name)

at this point, 'segmentation fault' is printed to STDERR and mythfrontend quits.
The return from the .configure script that is run by emerge shows
OpenGL turned off, and XvMC turned off.. so I'm not sure where we are
getting this, or even if we're looking in the right place.

I can read the stream off the card with mplayer, are there other
things I should be testing?

thanks for the help so far.
