Ok.. I am getting a 522 tomorrow.. it has the capability of 5.1 or PCM through its optical audio out. well my XBox (which i play dvd's on) also uses an optical out to do DD 5.1 or pcm. My reciever only allows 1 Optical cable at a time. Im not in the financial standing to go buy a 200+ dollar reciever jsut for 2 optical in's what (if anything) is on the market for not too much money that i can use to switch between the two or am i up a creek?
