You're right about the duel tuner option if it's a regular digital box, but if it's one of the DVRs they offer then it will have that ability. I can say with almost 100% certainty that the Manhattan area has not launched SDV. With that said it does not mean they will not be in the near future. I know that there are some areas in the country they are still beta testing the SDV on some DAC systems. Manhattan is using Motorola cards still if i am not mistaken which also means they are on a DAC system. It is however possible they have some overlay areas but not that i have heard of at this point. Overlay meaning where they are using both SA cards & Moto cards.
