I usually have to watch Breaking Bad with only the TV sound because my kids are in bed. But last night they were gone so I fired up the surround sound. Although much improved sound, I noticed the receiver was on "Stereo," and flipping through the audio options, Dolby Digital never came up. I am using a DirecTV HR34 DVR. So is AMC not broadcasting this in Dolby Digital? Or am I having a hardware issue?
