Summary
LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls.
Fedora Core 7 Install (Yum)
For Fedora Core 7 I used the atrpms repository. They have already built all the necessary binaries we will need for the installation. You can checkout their install page or follow the condensed instructions.
-or-
Install the GPG-Key:
rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms
Copy the text below into the following file:
/etc/yum.repos.d/atrpms.repo
[atrpms] name=Fedora Core $releasever - $basearch - ATrpms baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms gpgcheck=1 enabled=1
Install the needed packages with yum:
yum install lirc-lib-devel lirc-lib lirc lirc-kmdl-`uname -r` lirc-devices
Hauppauge WinTV-PVR-150, WinTV-PVR-350 Cards
Load the module for Hauppuage 150 and 350 PVR cards with the commands below and then restart lircd:
depmod -a modprobe lirc_i2c /etc/init.d/lircd restart
Enable Lircd on Startup
chkconfig lircd on
Note: See #Could not get file information for /dev/lirc (Lirc Reboot Errors) for a potential bug where Lirc doesn't work after a reboot.
Lircd Files
Lircd files map infrared hex singnals to key names.
Add remotes to the lircd configuration file:
/etc/lircd.conf
Note: Lircd should be restarted after any modifications to this file.
/etc/init.d/lircd restart
Hauppauge WinTV-PVR-150, WinTV-PVR-350 Cards
You can browse the remotes folder that is included in the lirc documentation for your remote control's configuration file.
cp /usr/share/doc/lirc-*/remotes/hauppauge/lircd.conf.hauppauge /etc/lircd.conf

Lircrc Files
Add commands to the default configuration file:
/etc/lircrc
Additionally you can use place the configuration file in your home directory:
Note: If this file is present it will override the file in /etc/lircrc
~/.lircrc
Note: Lircd should be restarted after any modifications to this file.
/etc/init.d/lircd restart

Some systems will fail to auto load the lirc module. There are various ways to fix this problem but I found editing the /etc/init.d/lircd startup script to be the easiest.
Edit: First 6 lines in the Start() section.
