In MythTV Setup, there is an important setting 'External channel change command' under 'Connect source to input' for each tuner card: We recommend saving several channel changing scripts - 1 for each device - then entering a different script name for each tuner in MythTV. Specifying Which Emitters before Changing the Channel If you have multiple set-top boxes, you'll want to limit the channel-changing scope to 1 device as to not interfere with other recordings. To select emitters with CommandIR Mini, make sure your script runs an 'irsend set_transmitters' command before issuing irsend's to change the channel. Eg: Sample chchangeon1.sh | # This is the script for controlling my first Scientific Atlanta set-top box on emitter #1 irsend set_transmitters 1 (the rest of the channel-change script follows). |
Then in the MythTV 'External channel change command' (as seen above) enter 'chchangeon1.sh '. Copying the file to chchangeon2.sh and changing the irsend line to 'irsend set_transmitters 2' will select the 2nd emitter, and so on. Download the CommandIR Mini MythTV channel changing script here. |
