hi, 

i'm attempting to run mythtv on a MPIA-M6000 running gentoo, making use of 
the CLE266 and a DVB card (running epia-kernel, and xfree-epia and the DVB 
drivers from cvs). 

After starting up mythfrontend and switching to Live TV, i get approx 4-5 
seconds of live tv before the frontend segfault's. 

i put mythfrontend through GDB, and here is the output.
(also, i re-emerged mythtv and put USE="debug" in the ebuild. I'm assuming 
that is the correct way to compile in debug through emerge???)
