I have a Pioneer VSXD508 receiver with a Samsung DVDS221 DVD player. My speakers are a JBL SCS125 home theatre package. I am getting a new RP set tomorrow and am trying to make the most out of my sound so I went out and bought a digital coax for the receiver to DVD connection and some component video for the DVD to TV. Question is, when I hook the digital coax to the DVD by itself I get no sound at all. I have to hook analog cables to it for it to work. Did I waste 20$ on a cable? Seems like all the manuals say I should be able to hook up a DVD directly and have sound, I tried a 5.1 DVD and a CD but no luck. Secondly, my speaker set usually gets hooked into the subwoofer and then into the receiver but it says it can also do line connections. I can connect the satellite speakers to the receiver fine but the subwoofer has two line outs (R/L) and my receiver doesnt appear to have any subwoofer line outs. It has a single sub pre-out but I tried hooking into it and it does nothing. If I hook the line ins to the receivers other line outs with L/R channels (like VCR) it works but I am afraid that I am going to damage something in the process. Anyone have some advice?
