Has anyone worked out how to switch the amp on as part of a multi operation? I'm trying to program the remote to do the following: 1. Switch on the plasma 2. Switch on Sky 3. Switch on the amp 4. Select input 1 on the plasma I can do items 1, 2 and 4 but I can't work out how to switch the amp on. It's not possible to select the Receiver power on/off as an operation... Anyone?
