Channel Changing Script for CommandIR Mini with MythTV and Multiple Set-top Boxes

• Note: This is not required for CommandIR II. CommandIR II can control all 4 devices at the same time without interference.
• This channel change script includes a 'lock' mechanism to ensure the commands to each set-top are transmitted in the correct sequence and to the correct device.
• See MythTV Channel Changing for installation instructions.
