Not sure if this is possible. Cutting D* cord soon. Have coax from outside to all locs where TV's are now, but only HDMI cable from where the D* boxes are up thru pipes to TV on wall. When I put up my digital antenna, bring it in via the coax, is there an adapter to convert to HDMI, so I can use the HDMI cable thats already there? Not really a big deal I guess to run coax up to TV's, just something else to do. Thanks for any replies/wisdom
