I have Sony's 500W system and I want to connect my PS3 and Xbox 360 to the receiver. The problem is that the receiver only has one optical input. Now, I've found a couple of solutions that may work. I've read about an optical selector switch that lets you have multiple devices plugged into one optical input. I've also read about an optical to digital coaxial converter. What I'm wondering is if either of those options are feasible and if they'll work well. I would appreciate any suggestions.
