The input list for the Clone has 2 entries - Analog and Digital. Analog tuner is one input, digital tuner is the second input. You cycle between the 2 inputs using the TVMode button (or whatever it's called). It's no different than having 6 different inputs - it works the same either way. You press a button to cycle through the list of inputs.

I think you're viewing both analog and digital as ONE input because it uses ONE button, but in reality it's two different inputs that use one button to toggle between them.

Do what jlet suggests for further clarification.
