[mythtv-users] 3D (OpenGL) on an M10000/Gentoo setup

[Travis Kelley]

One more quick question.  I'm killing myself trying to get lirc working
here.  Did you emerge the lirc that comes with gentoo?  If not which
lirc are you using.  Also could you attach your /root/.mythtv/lircrc &
/etc/lircd.conf & /etc/conf.d/lirc*

I had lirc working without a problem on my old box so I assume its a
configuration issue somewhere, but I've been working on it on this box
for a couple days now.

Thanks for your help so far!
