Just want some clarification about the Zone 2 function on the 990.

My question is...can ANY source be used in Zone 2? I assume so, but what's got me confused is the limited number of sources available on the Zone 2 remote. Are those the ONLY sources available to Zone 2?

And adding to that, how easy is it to select the Zone 2 source (using either remote)? From reading the manual it looks like you really need to have the TV on and do it with the on screen..is that true? Can it be done without turning on the TV? This is an issue for me because my TV is not really a TV, it's a projector. I don't want to have to turn it on and wait for it to warm up every time I simply want to change my Zone 2 source.

On my current system I just press the 'zone 2' button, then press the button for the input I want..either on the front of the unit or with the remote. Is the 990 this simple?
