[mythtv-users] LIRC: Beware of brain-dead packagers! (was: Lirc problems w/PVR-250)

I found that this problem occurs if ivtv is not loaded.  lirc worked for
me when I followed Jarod's instructions, but then, after rebooting, it no
longer worked.  lircd quit as soon as I launched irw.  I spent hours
trying to figure this out.  The solution is to make sure that ivtv is also
loaded.  The ivtv kernel module must be loaded first--it is needed to find
the IR device.

Another way to confirm that the device is not found is by cat'ing=20
/dev/lirc.  If it says something like "no such device", then that's=20
exactly what the problem is.
