I am on the fence about buying a Series 3 or HDTivo, though I want one very bad. Cablevision of Long Island is my provider and they will be rolling out SDV at some point in the near future. Does anyone know if either the Series 3 or HDTivo will ever be able to receive SDV channels via a software update?? I keep reading that the cable companies are supposedly working with TIVO on a solution, but no one ever says if the solution will be a brand new box or a software upgrade to the existing units out there. If I knew for certain that a software upgrade would solve the problem, I would buy one tomorrow. Anyone have the answer??
