We are about to get a tv for a spare bedroom and want to wall mount it. If I order a HD receiver from D*, am I likely to get an H25? I understand these are nice and small and can be mounted behind the tv using rf for the remote. Are the other receivers also rf compliant? Second question: for WHDVR, is a DECA required for the Hx? (I know that the dvrs need them as I have them on my three HRx dvrs.) Thanks for any advice/suggestions.
