This may be what was experience and led to Trac #195:
http://svn.linuxmce.org/trac.cgi/ticket/195I did a fresh 810 install and configured the Hauppauge PVR-150 on my M3A78-EM:
http://wiki.linuxmce.com/index.php/ASUS_M3A78-EMWhenever I click "TV" from the main screen the my loading bars will go to 100% each, then the screen will go black for 4 seconds after which time the cursor will appear (the single arrow, not the 4 arrow cursor) and 2 seconds after the UI screen will appear with the 4 arrow cursor hovering over the now playing box.
When I try to run mythtv from the desktop it errors out with a "segmentation fault (core dumped)"
When I went to "computing" "mythtv setup" "general" there was no Security Pin. I entered "0000', but this does not seem to make any difference.
What I find even more odd is that mythtv works great on 2 other MDs. There is only the one PVR-150 for the system and it is installed on the core.
Any ideas?
