New DirecTV customer here. I need some suggestions regarding my issue. Our home was pre-wired, and the only spot for our TV downstairs is above the fireplace. The problem is that they installed a tiny conduit from above the fire place to the built in cabinets and it cannot fit more than one HDMI cable. I would like to have our receiver and blu ray player hooked up to the TV without having to constantly switch the HDMI cable back and forth. Which would be the better option: install an HDMI switch for the receiver (H25) and 3D blu-ray player to share? Or to use HDMI over cat5/cat 6? I'm pretty sure I can squeeze two cat5/6 cables in the conduit in addition to the existing HDMI cable already in there. Any help would be appreciated.
