I have my Logitech 550 Harmony Remote not working properly. I have it set to 'Watch Tv' and 'Watch DVD', but when I click the buttons to do the commands, it switched over the TV Input, and it doesn't switch over the audio input.

I checked the software, and it says it is set to switch between the Aux and TV input when I choose the activity I want, but it never switches!
