If your remote responds on screen with irw but not inside MythTV, you may not have finished the entire setup. First of all, if you're using irexec, I wanted to say that irexec only translates your button signals into a command. This means that you may very easily use irexec to start MythTV with a single button, because starting MythTV is as easy as typing mythfrontend in a terminal. But programming your entire MythTV controls with irexec is a bit of a challenge. Perhaps, it may be as difficult as having to assign each remote keys to a macro of keyboard commands while considering the window session focus. I'd say this method is not impossible, but a challenge. I haven't tried, of course.
The following method is one that I find to be easier, but not yet well documented (neither is the one mentioned above, really):
As stated above, if you haven't done so already, you'll need to re-compile MythTV with the USE flag lirc.
Believe it or not, you're still not quite finished yet. Now, you need to tell the mythtv-lirc-module (not lirc itself) about your remote control button configuration. This means population of the MythTV LIRC config in $USERNAME/.mythtv/lircrc, where $USERNAME is the user running the mythfrontend interface.

After you've placed this code into the mentioned file (with enough of specific), try restarting mythfrontend. You may have to enter the LiveTV mode to test if the number buttons actually work. Try channel 2 with the (button 0) (button 2). Try channel 21 with (button 2) (button 1). If it does, then go along and set up the other numbers as well as the MythTV functions. (These can be looked up in the MythTV documentation) Well, I wish you luck. It took me too long to find this out.
lirc (getting the remote to work)
First, we need to make sure the proper versions will be installed, and compiled with the proper options. If you've done this already you can skip this and go directly to "Emerging". Also see: LIRC
Options and unmasking
If you're emerging LIRC < 0.8.0-r1
echo 'LIRC_OPTS="--with-driver=hauppauge"' >> /etc/make.conf
Otherwise add the lirc_devices_hauppauge to your use flag
echo 'LIRC_DEVICES="hauppauge"' >> /etc/make.conf
[ ! -d /etc/portage ] && mkdir -p /etc/portage echo 'app-misc/lirc ~x86' >> /etc/portage/package.keywords
(note: If the first line is omitted the package will only compile the lirc_serial driver. In order to get the lirc_i2c driver needed for the Hauppauge cards this line must be included. If you have one of the hauppauge dvb cards like the Nova you will need --with-driver=hauppauge_dvb. In case you have an hauppauge mce card with usb connection for the ir blaster, you will need the mceusb or mceusb2 driver, so --with-driver=mceusb or --with-driver=mceusb2. The module will then be called lirc_mceusb or lirc_mceusb2. For example, the PVR150 MCE works with the mceusb2 driver.)
Now we need to emerge lirc and copy some config files:
emerge lirc rc-update add lircd default
Setting up /etc/conf.d/lircd
Check the name of your lirc socket and character device:
localhost ~ # ls -la /dev/lirc* crw-rw---- 1 root root 61, 0 Apr 10 02:57 /dev/lirc crw-rw---- 1 root root 61, 0 Apr 10 02:57 /dev/lirc0 srw-rw-rw- 1 root root 0 Apr 10 03:34 /dev/lircd
Verify that /etc/conf.d/lircd is set to the character device.
# If socket is /dev/lirc0 LIRCD_OPTS="-d /dev/lirc0"
If you're using udev (version > 2.4), the device will be:
If you change /etc/lircd.conf, you'll need to do this to use the new configuration.
Make sure the appropriate modules have been inserted. I'm using the pvr-250 IR remote and it needs the lirc-i2c module. To insert the proper modules, type:
and that should insert the module for you.
If you want to load the module automatically after a reboot, don't forget to add the module to /etc/modules.autoload/kernel-2.<your version here>, i.e: /etc/modules.autoload.d/kernel-2.6 or /etc/modules.autoload.d/kernel-2.4 depending on your kernel version.
Setting up /etc/lircd.conf
Now we need the configuration file for your remote.
If you are not using a Hauppauge remote, check http://lirc.sourceforge.net/remotes/ or http://lircconfig.commandir.com/lircd.conf/ to see if there is one available for your remote otherwise you will need to create the /etc/lircd.conf file using irrecord.
There appear to be 3 versions of the hauppage remote. If you have the newer versions of the hauppage remote which is grey on top and black on the bottom then you can get a replacement for the /etc/lircd.conf file here After you've replaced the file re/start lircd. If you have either the pure black or gray remote, apparently the included lircd.conf file works fine but I don't own one so I can't test it.
or try here: http://lirc.sourceforge.net/remotes/hauppauge/ for more remote control configuration options. (Carter) I have a gray top, black bottom remote from the WinTV PVR 350. I used the lircd.conf.hauppauge file from the sourceforge link and things are working fine for me. (DeKay) I also have a gray top, black bottom remote but it is from a WinTV PVR 150 MCE. It has "RC6" printed on the back and did not work with any of the configurations in the default /etc/lircd.conf file. I had to use the version from here
To create your own /etc/lircd.conf file: (use the character device for the --device option)
irrecord --device=/dev/lirc0 /etc/lircd.conf
The irrecord program will record the signals from your remote control and create a config file for lircd. A proper config file for lircd is maybe the most vital part of this package, so you should invest some time to create a working config file. Check out http://www.lirc.org/html/irrecord.html for more information on how to use irrecord.
Testing the remote
And push some buttons. You should see output. If you don't make sure you have the proper /etc/lircd.conf file for your remote.
Specially for av7110 (Hauppauge Nexus-s) cards
You have to do some special things to get this RC working:
av7110_loadkeys <location>/hauppauge_grey.rc5 > /proc/av7110_ir
The loadkeys-script and the rc5-file can be found in the linuxtv-dvb-apps package at linuxtv.org
Power button to turn on mythfrontend
If you wish to use your Power button to turn on mythfrontend incase of crash you can do so by adding 'irexec --daemon' to your startup and add the following to your ~/.lircrc (this applies to hauppauge remotes, adjust as needed)
begin button = Power prog = irexec repeat = 0 config = mythfrontend end

A free tool for configuring remotes for MythTV can be found at http://lircconfig.commandir.com/.
Remote config hauppauge
Basically, there are two ways to run mythtv with a remote, you can:
1) compile lirc support into mythtv and create a ~/.mythtv/lircrc file. NOTE: This requires setting the USE variable: lirc
2) create a ~/.lircrc file, and run irxevent to map IR signals to x-events while mythtv is running.
A sample config for your remote. This uses mythtv as its backend. This file should be ~/.mythtv/lircrc (note lack of .) for the user that runs mythfrontend.
Unfortunately, at the moment it doesn't seem to be possible to map ctrl-key keypresses using lirc. The syntax to map Ctrl-Q to the Off button should be the following, however it doesn't currently work.
begin prog = mythtv button = Off config = \Q end
This is because mythtv uses QT key names. This works:
begin prog = mythtv button = Off config = Ctrl+Q end
See the Hauppage .mythtv/lircrc example
A sample config for your remote. This uses irxevent as its backend (as in you should include irxevent & in your .xinitrc). This file should be ~/.lircrc for the user that runs mythfrontend. Hauppage .lircrc example
NOTE: If you are seeing an error when you start MythTV (mythfrontend) complaining about an invalid file format for .mythtv/lircrc, it may be because the file has DOS/Windows-style line breaks. You can confirm this by opening the file in vi (you may need to emerge vim) as a binary file:
vi -b ~/.mythtv/lircrc
If you see an extra ^M at the end of every line, then you have DOS-style line breaks. To fix this in vim, enter the following in command mode before saving:
