I still don't get why people think doing this (and repeating it with 
each upgrade--and on each system) is easier than creating (or, likely, 
downloading) a single LIRC configuration file for the remote 
(lircd.conf) and a LIRC configuration for MythTV (~/.lircrc) and any 
other application you want to use with the remote, which can then be 
backed up with your other configuration files and just dropped in place 
whenever you upgrade your distro or set up a new system or...

Sure, getting LIRC working once took some learning, but once I finished, 
I forgot /everything/ I ever knew about configuring LIRC and haven't 
worried about it since I first set it up in 2004.  All I remember at 
this point is just how sensible LIRC's abstraction is--allowing me to 
configure applications individually independent of the specific remote 
I'm using and without having to remap remote buttons for a specific 
application (and make them crazy mappings for other apps) or without 
having to remap application buttons (and mess up keyboard mappings at 
the same time).

And since modern distros that are a good choice for MythTV (i.e. *buntu 
and Fedora and possibly others with excellent repo/configuration support 
for MythTV) actually allow you to just select a remote so it can set it 
up for you, things should be a lot easier now than they were in 2004.

But, hey, at least you can say, "I finally set up my system and I don't 
/have/ to use Linux Infrared Remote Control to, support my, er, ... 
infrared remote control in ... Linux."

Help!  There's a baby going down the drain with that bath water!
