Finally configure MythTV to use your IR Blaster. For this step you just need to make a simple

bash script like the following…

#!/bin/shREMOTE_NAME=SA2000 #Name of the remote in /etc/ledxmit.d filefor 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 modelDone
