Hey guys. I need some help hooking up my home theater system to get my TV/Cable/PS3 to play through my Home Theater. I HAVE - 42'' Sanyo DP42841 RCA RTD317W ---- http://www.walmart.com/ip/Rca-Home-Theater-Upconverting-DVD/11319409 PS3 I have a HDMI Cable, RCA Cables (5plug), and a single video cable that came with the home theater system. I can purchase whatever else I need to make this work. AUX IN - AUD IN - OPTICAL - DVD -TUNER -- These are my selections for input on the RCA system. Has a 3.5mm jack in the front as well. PLEASE HELP ME MAKE THIS WORK! I can't for the life of me figure it out, and the two people at walmart I spoke to obviously didn't know what they were talking about. Thanks everyone! PS, it works great with a DVD in, but that's all I can get to work haha.
