I am looking to upgrade to the Genie whole home dvr and wanted to know if I understood the wiring that would be needed. I currently have two tvs each with a receiver that is fed by two coax cables from the satellite. I assume there is a splitter at the satellite. I'm pretty sure that I will need to have a new satellite installed to upgrade to SWiM in order to support the HR54. Currently to both rooms with a tv I have 2 RG6 cables for satellite one RG6 for off air antenna, and one Cat6. In room 1 I will have 1 tv connected directly to the HR54 with HDMI. The HR54 will connect to the coax to the satellite and to the internet with the cat6 connection. In room 2 I have a directtv ready tv this can be connected tot he HR54 and the satellite with either the coax to the satellite and a deca converter to ethernet, or I could just use the cat6 connection to my network? Is this correct? Would it be better to connect to the internet network in my house or connect over the coax network to get this tv working. I also have an am21 off air tuner, would this go between the coax connection to the satellite and the HR54 or would I need to do something else to get the off air tuner working on both tvs and directtv? Anything else I need to think about.
