Within the last 2 weeks my HR44 Genie stopped recognizing my AM21 Tuner. First I thought it was my antenna, so I bought a new Mohu Leaf Antenna, it wasn't the antenna. Then I bought a new USB cable, not that either. I then noticed that the Antenna setup is no longer in options and the receiver got an update 2 weeks ago. I know Directv stopped supporting the AM21s but is this an issue with anyone else?
