I have a LG 42 LW65oo 3D TV which has HDMI/DVI IN 1 (ARC) and another three HDMI/DVI IN Ports(2,3 & 4). I also have a Sony 3D Blu-ray System BDV E880. This has a HDMI OUT ARC and two HDMI IN (1 & 2). I also want to connect this system to Tata Sky DTH cable connection. Tata Sky has got one HDMI port, one SPDIF Optical port and Audio OUT ( L & R ) and Video OUT connectors. The LG TV also has a Optical Digital Audio OUT port and Sony BDV E880 has a Digital Optical IN. Kindly suggest me the Best connection scheme for Best Audio-Video.
