Perhaps you are talking about "CableCARD". The problem with this device is that the cable TV companies have been dragging their feet to get it (or allow it) implemented. They just love being in control and "renting" those cable boxes to people every month. Now that CableCARD is out there, albeit on a limited basis, we find it does not allow certain functionality. But a software soultion is being rolled out which does not have the same limitations.
