For DirecTV Genie HR54 Remote - TV Functions, relating to DirecTV DVRs and receivers. We had DirectTV installed yesterday with a Genie HR54 and given RC73 remotes. The remotes work our volume and power. Our Uverse remotes we able to control functions on our Sony TV i.e. the sleep timer, inputs, etc. Is the RC73 capable of controlling our Sony Bravia or is there a universal remote out there that can control DirecTV's Genie HR54 and other componets?
