[mythtv-users] Lirc - could not open /dev/lirc

[johnny at fishcounts.com]

I don't know if this will help or not but when I had that problem 2 days ago
with my x10 lola for some reason lirc was saying my remote codes were
different than what they were when they were working before my upgrade. I
did an irrecord and pressed several buttons and I noticed they were pretty
much all different. I remade a new lircd.conf and restarted lircd then irw
showed the proper button presses.

That is the same exact symptom that I have. Strange.  I also have a 
FC2,. PVR-250 and the latest ivtv/mythtv from ATrpms. The only thing 
different, I believe, is that I have to stop lircd first before I 
depmod/modprobe and restart lircd.

I too wish I could find out why this is, too. I'll monitor this post!
