I have a wall-mounted TV with a chase in the wall to fish wire and cable. I have a 18-foot HDMI line connected to the TV and DirectTV box. I now need to connect my Blu-Ray player to the TV. Do I need to use another separate 18-foot HDMI cable or is there a coupling or box that shorter lines from these different components be plug into, so that only one long HDMI cable is needed?
Thanks for any comments.
