Thank you for your prompt input. I think I understand your comment "...the number and order of the inputs on the TV match the number and order of the inputs in the remote software... " because I have gone through the lists on the TV and of the Harmony webpage several times. However, I don't understand "...that the commands used to select inputs are correct." Do you mean that the software commands have to have exactly the same name and spelling as the list of inputs in the TV? Perhaps you could clarify that for me. And, sorry for my profound ignorance, but what is "...a cycling method..."?
