Switching to any inputs with the on or off buttons is pointless. It is assuming you know what the user wants to watch. On and off should do nothing more than turn on and off devices. Source selection buttons should do the input switching. The only acception is when it is in your house and you know what you want it to do. ie, in my house "on" is the same as pressing the cabletv button because it is all my wife watches. If I want anything else I won't press on, but instead will just select the source.
