Before reading your answers to my post I started using the AUX out for the analog audio input to my TV. The only drawback is I have to bypass the pass-through for audio control and use the TV for control of the audio. I assigned Video 1 to the TV which uses the DVR component input with the trigger off. I create and another DVR control, almost identical, but uses Video 4 with the trigger on and using the optical input instead of analog as with the Video 1. What benefits would using Zone 2 over this method get me?
