I'm having D* installed at my mother's house on July 5th. She's got 3 HDTV's & 2 SDTV's. We're getting HD & Whole Home, etc. so I'm curious as to which SD Receiver & SDDVR she will get. She's in Memphis in the 38141 zip code. Will the SDDVR still require two lines or since this will be a SWM install will it use one line like the HDDVR's. I've got more questions about the install but I'll post those in another forum.
