Hi! I wonder if anyone can help please... I have a DVD player and a DVD recorder. I want to be able to connect both of the coax outputs into my amp, but it only has one coax input. The optical input is already taken up by the satellite. Does anyone know if I could use some kind of 2-into-1 device to achieve this? Or am I going to risk damaging one of the players? The DVD players have optical outputs as well. Thanks!
