Here's my situation: I have an older Onyko A/V receiver with one digital coaxial input (the optical input is broken). I have 2 components with digital coaxial outputs (dvd player & directv receiver) that I would like to utilize. Is there such a thing as a simple, inexpensive "2 inputs to 1 output" adaptor, cord or switch that would work for me & still maintain the digital sound integrity? It seems to me that this would be quite easy but I can't seem to find such a product. I've seen many simple optical splitters but not coaxial. Thanks a lot.
