I am looking into my first surround sound system and one of the features i find desirable is HDMI pass through in standby, enabling me to watch and listen to the TV with the receiver in standby, thus saving power when watching basic TV programs. When reading a recent thread, I started to think that this is not as simple as I first thought. My equipment would be TV - Sony KDL-40d3000 (4 yrs old), Marantz NR1602 or Yamaha RXV671 receiver, Virgin V+ box, Sony Hard Drive DVD recorder, XBox and Blu Ray player (to be decided). I assumed that I would just connect up the equipment with HDMI leads, set up the receiver to enable pass through, then all would be good. maybe it would only pass through the signal from the last device used, but that wouldn't be a problem. Then I read about 'CEC' function on components to be connected and start to wonder what all this means, particularly on the V+ box, through which most of the TV viewing is done. Can someone please enlighten me as to how simple or difficult this can be.
