Also, unless your TV is slow to switch inputs or it does not have discrete codes for inputs, I wouldn't bother tracking the inputs. If neither of those are the case, I would only track the TV's power. As long as you have discrete codes for inputs, and the TV switches inputs pretty fast, the benefit of tracking inputs isn't worth setting up the variables and if/else statements it requires.

When you set up your macros that include if/else statements concerning the TV power variable, you need to figure out the time delay the tv requires between powering up and accepting an input command, then set up the macro like this:

If variable TV power is FALSE
TV Power ON
Delay x.x seconds
Else
---------------------
TV Input x

Set it up like this and you don't have to have the input command in both the IF and the ELSE portions of the statement, i.e.

If variable TV power is FALSE
TV power ON
Delay x.x seconds
TV Input x
Else
TV Input x
