This might help... The newer set's (xxH81) DO have discreet power, but we all know the older set's don't. As far as the discreet inputs go, you can use a workaround. If the TV is on any input, you can issue a channel up or down command. This will reset the input of the TV to ANT. You can then toggle through the inputs until you reach the one you want. Example... When I want to watch my DVD, I want my IntelliControl to switch it to Colorstream 1, no matter what input I'm currently on. I will issue a channel up command, and then 3 input toggles to reach the Colorstream 1 input.
I hope this helps. -Brian.
