Check /var/log/lircd.  You should see something like this when 
mythfrontend starts:

Sep  4 22:03:42 myth lircd 0.7.0pre7: accepted new client on /dev/lircd

and something like this when mythfrontend exits:

Sep  4 22:03:02 myth lircd 0.7.0pre7: removed client

You should see the same thing when irw starts and ends.  If you do see 
these messages with irw, but not with mythfrontend, my suspicion would 
be that myth is not compiled with lirc support.  If you do see these 
messages with myth, try the next test:

Temporarily rename your ~/.mythtv/lircrc file to something else, start 
mythfrontend in the foreground, and look at the output.  You should see 
something like this:

2004-09-04 22:17:47 mythfrontend version: 0.15.20040528-1 www.mythtv.org
2004-09-04 22:17:47 Enabled verbose msgs : important general
mythtv: could not open config file /home/myth/.mythtv/lircrc
mythtv: No such file or directory
Failed to read lirc config /home/myth/.mythtv/lircrc for mythtv
2004-09-04 22:17:48 Registering Internal as a media playback plugin.

The presence of this error message is another way to verify myth has 
lirc support compiled in.  Also you can use it to make sure you've put 
your lircrc file where myth is actually looking for it.

If all that works out OK (don't forget to put your lircrc file back to 
its original name), sanity-check at least one of the keys in your lircrc 
file:

begin
    prog = mythtv
    button = Ch+
# This is the "up" on the central diamond
    repeat = 2
    config = Up
end

Then check it against your keybindings in the database:

% mysql -u mythtv -p****** mythconverg

mysql> select * from keybindings where keylist = 'Up';
+-------------+-----------+-------------+---------+----------+
| context     | action    | description | keylist | hostname |
+-------------+-----------+-------------+---------+----------+
| Global      | UP        | Up Arrow    | Up      | myth     |
| TV Playback | CHANNELUP | Channel up  | Up      | myth     |
+-------------+-----------+-------------+---------+----------+
2 rows in set (0.00 sec)

And finally, start mythfrontend, press the up-arrow key on your 
keyboard, and verify that myth actually does what you think it's 
supposed to do when you hit the CH+ (up arrow) button on your remote.
