Dish's AirTV Player is an intriguing mix of an over-the-air player with streaming services, but that single tuner has made it difficult to recommend if you want to both record and watch live broadcasts. You won't have to make that compromise from now on, though, if you're willing to pay. The company has launched a dual tuner adapter that enables simultaneous recording and viewing, or recording for two channels if there are two must-see shows you're going to miss.
