I just bought a 5.1 LG Blu-Ray home theatre for my 47 inch LED TV. I was wondering, how do I get surround sound for my cable tv and my PS3 and not just from the LG Blu-Ray? I need to hook my set top box and PS3 to the Blu-Ray then hook the Blu Ray to the TV, right? Only problem is the Blu-Ray only has 1 HDMI out jack to go to the TV, and 1 HDMI in jack......does that mean I can only hook up either the PS3 or the set top box? This shit confuses me.....much help would be appreciated.
