Folks, The more i read the more confused I become. Here is my system: PC with all my music and DVDS and a Sound Blaster2 card with Digital out, as well as 2 rca jacks. I want to push sound (and video signal-via a cat5 converter)to my Intergra DTR6.4 AMP which has Digital audio input (labeledOptical).. QUESTION : what cable(s) AND connectors do I use to transport sound (5.1) to the AMP? PLEASE HELP noob in deep water.......waving
