I maintain a small analog headend for a 400 unit retirement home. Its channel lineup includes about ten local broadcast channels and about 40 analog channels that are modulated from DirecTV receiver's A/V outputs. The manager there asked me what was available for what he called, "TIVOs", which to him and a lot of people, is like asking what kind of Xerox machines are available. Or like my French Canadian grandmother shopping for a "frigidare". How difficult is it to program a DVR that isn't connected to a DBS provider or franchised cable company source. For what it is worth, I expect to be adding a DirecTV L-band overlay to this system, allowing the residents to use DirecTV receivers over the same wiring, so if DirecTV's DVR is capable of recording analog signal and is fairly easy to use, I'd probably steer the residents in that direction.
