I only have one coaxial input on my receiver. Is it possible to increase that or a switcher or some sort or would I be better off buying a new receiver which I'm planning to do? I have my DVD hooked up to the coaxial input and I have an Xbox that requires an optical connection. What can I do? I don't have any optical inputs and I maxed out my coaxial connections on my receiver. I am better off getting a new receiver right?
