my yamaha rxv 2400 reciever has 1 set of 5.1 anolog inputs and no hdmi. i just orderd an a2 figuring i would have to use an optical line with it becuse my anolog inputs are reserved for the new pani 10a bd player coming out. but i really want the new audio formats for both bd and hd-dvd. im willing to return the a2 and get the xa2 if there is a way to do this. any ideas?
