Watching a movie or your favorite television shows on DirecTV not only gives you a great picture, but it also gives you digital audio with surround sound options such as Dolby digital and DTS that make the sound as important as the picture. To take full advantage of the digital audio quality, you will want to hook up the DirecTV receiver to your home theater system. Doing this will allow you to enjoy the total experience of DirecTV's digital technology.
