This year for the holidays I bought myself an HDHomeRun Prime by SiliconDust. Comcast gave me an M-card with no questions, and the tech support number in the documents (a call center that does only Cablecard activations) handled the activation fine. It would have been somewhat easier if there were a decent online description of exactly what numbers the call center needed. Three independent tuners, DLNA compliant, and delivers the HD streams over our household LAN (some wired, some wireless). Works fine to my Mac and my Android phone. There are issues with my old Android tablet, but those involve the limited hardware there, not the delivery.
