Use LircChannelChanger to change channels

Use this script to change channels

But, change line 803 from this:

 cmd("$irsend $irsendoptions SET_TRANSMITTERS $emitters");

to this

 # cmd("$irsend $irsendoptions SET_TRANSMITTERS $emitters");

LircChannelChanger config file

#
# Configuration file for the LircChannelChanger script
#
# Except for the configfile option, all other options
# specified on the command line can be specified in
# this file.  Comments ('#') are stripped, and options
# that are not prefixed with '--' have the '--' added.
#
# The main reason for supporting a configfile is
# that the command line for the LircChannelChanger script
# could exceed the 128 character (database) size limits
# if many options were specified (and fully typed out).
# In particular, the before or after commands with long
# remote strings.
#

                            # so sending 0 requires the name KEY_0
#beforekeys      KEY_INFO    # Return from extended info screen, if on it,
                            # otherwise this puts up the channel info,

MythTV Backend setup

You need to configure your analog input device to use the channel changer script

e.g.

Input Connections: /dev/video2
Display name: Hauppauge 1950
Video Source: cable box
External channel change command: /usr/local/bin/LircChannelChanger --cf=/etc/lirc/LircChannelChanger-DTA.conf
Preset tuner to channel: 3
Scan for channels: us-cable
This will find channels from 3 to 116.  You will have to edit and update these later
