Ok, so here's my situation. I currently have one of those Sony "home theater in a box" systems with a low end digital receiver with only one digital coaxial audio input. Right now, as you would expect, the wire plugged into it is the audio from my DVD player. But I also want to plug the S/PDIF audio out from my old computer into the receiver as well. Is there a way I could have them both going into the receiver at the same time without losing the "digital-ness" of it all? That is, I've heard that if I just use a regular RCA splitter that I will be turning the signal into analog or something. A switch would also be fine as well, though all the ones I've seen are for 4+ inputs and are way pricey. I'm just looking for a way to avoid having to change the connection every time I switch between PC and DVD player. (One other alternative is to use an optical cable to from my DVD player and the coaxial from my PC, though I've heard optical is inferior...is this true?) Any help would be greatly appreciated!!!
