I have earlyxdm disabled in opensuse 11.3 for my mythtv frontend, it is
still needed because lcdproc and lirc refuse to work properly when I leave
it enabled.
(lcdproc depends on lirc and is needed for the display on my antec veris
box)

Ok if irw gives output when you pres a key your remote and reciever are
working.
Did you put the proper configuration file for the remote in /etc/lircd.conf
?
That is the file that defines which hex code belongs to which key.
It has nothing to do with myth yet, but it is required.
example configs are provided by the lirc-remotes rpm.
Zypper should be able to find that one.
The rpm installs the examples in /usr/share/lirc/remotes
You already have created an lircrc file in the .mythtv.
Put it in the homefolder of the user that you use to watch mythtv.
/home/user/.mythtv/lircrc
In mythtv
utilities/setup->setup->general->8xnext
make sure the path to the socket is correct
verify if the socket is there
ls -als /var/run/lirc/lircd
notice that the group of that file is video ( I think this is your culprit)
add your mythtv user to the video group
and add the mythtv user to the audio group as well (I did that because it
prevents errors in the mythtv logs)
The option LIRC keypress application is there in case you want to run
scripts like irwatch.
But I think adding mythtv to the video group will solve your problems, since
you need to be a member of that group to access the socket.
And by default myth is not a member, so that could explain your problem.
sorry about not mentioning it earlier, it is typical one of those settings
you do 4 upgrades ago and completely forget about.

here's some examples from my config
It's not the full config (300+ lines) but I made sure the important begin
and end tags are there.
There are 2 modes for the veris rm200, one in which it acts as a normal
remote, and one in shich it acts as a mouse and keyboard which is usefull
when for some reason you are dumped to a login screen and are to lazy to get
up to press the power button.
Notice the extra begin and end entries for the modes to deal with this.
The first block makes sure the system starts in ordinary remote mode, the
key to switch mode is defined last.
begin
flags = startup_mode
mode = mythtv
end
*begin mythtv*
begin
remote = Antec_Veris_RM200
prog = mythtv
button = KEY_7
config = 7
repeat = 0
delay = 0
end
begin
remote = Antec_Veris_RM200
prog = mythtv
button = KEY_PLAY
config = P
repeat = 0
delay = 0
end
begin
remote = Antec_Veris_RM200
prog = mythtv
button = KEY_NEXT
config = Z
repeat = 0
delay = 0
end
begin
remote = Antec_Veris_RM200
prog = mythtv
button = KEY_PREVIOUS
config = Q
repeat = 0
delay = 0
end
begin
remote = Antec_Veris_RM200
button = MouseKeyboard
repeat = 3
flags = mode
mode = X11
end
* end mythtv*
*begin X11*
begin
remote = Antec_Veris_RM200
button = MouseKeyboard
repeat = 3
flags = mode
mode = mythtv
end
*
end X11*
