What is the model number of your TV?
Did you try all the commands in device mode?
Many devices support discrete commands although they may not be on the original remote.
If you have to use the cycling method, check if the "InputNext" command can cycle through all inputs.
If you have to use 2 cycling commands, then add another TV device. Decide which of the 2 devices will be the main device. The other one will be the clone. Set the input settings of one device to do the Input video cycling and the other device to do the Input PC cycling. Use Method 1 for both. Don't forget to answer the questions correctly (does it skip over inputs, and does it stay or goto a particular input on power up). Set the power settings of the clone device to "There are no power buttons". The main device will be used to control power. For activities using the inputs of the clone device, add the main device using the activity add device feature by selecting option "Yes, I want to add more control..." in the activity wizard or activity review, and tell it you don't need to set input on your added device (Main TV device).
