After several months of private testing, followed by an open beta, DirecTV has formally introduced their whole-home DVR service. As a fan of the ‘hub and spoke’ digital distribution model, the MoCA-based solution looks quiet compelling. Of course, DirecTV subscribers would need at least one HD DVR. But each additional room (up to 15!) can be outfitted with a less pricey HD receiver to schedule or view recordings from the primary DVR. Free would be nice, but you really can’t go wrong a low $3 monthly surcharge.
