The Finished Product:
Configuring LIRC for Transmitting

Get LIRC 0.7.0 and myth-ledxmit which are
both available Here
 Follow the instructions on how to configure
myth-ledxmit


This creates a second instance of LIRC demon
that controls transmitting IR Signals
Find a suitable Remote configuration file for
your cable or satellite box. Available from
http://lirc.sourceforge.net/remotes/

Copy this conf file to /etc/ledxmitd.conf
Configuring LIRC for Transmitting

Finally configure MythTV to use your IR
Blaster.
 For
this step you just need to make a simple
bash script like the following…
#!/bin/sh
REMOTE_NAME=SA2000 #Name of the remote in /etc/ledxmit.d file
for digit in $(echo $1 | sed -e 's/./& /g'); do
/usr/local/lirc-ledxmit/bin/ledxmit-irsend SEND_ONCE $REMOTE_NAME $digit
sleep 0.4 # note, you may have to tweak the interdigit delay up a bit, depending on your
receiver model
Done
/usr/local/lirc-ledxmit/bin/ledxmit-irsend SEND_ONCE $REMOTE_NAME SELECT
Configuring MythTV to Change The
Channel
Save your bash script and name it
