You still wouldn't get 3 zones, just 2. There's no way to make a 2 zone capable receiver do 3 zones; it's just not in the software. There's also no way to make a 1 zone (ie, stereo) receiver do 3 zones. Unless you run zone 2 from the speaker outs on the Onk, then run a line level cable from the onk to the stereo (in room 3) on the aux setting, for example. Then hook an ipod dock (or a cd player, or something) to the stereo in room 3 to play something different on that. It's not really 3 zones, but it's as close as you're likely to get without buying a new AV receiver.
