Grrr…. DirecTV

We have DirecTV in our house: 3 RCA recieved and a Samsung DirecTIVO. Since about 5pm last night, every receiver (all four) have been “Searching for Satellite Signal” only on the four Sho channels: 537, 538, 539, and 540. Called the dweebs at DirecTV. First, they think it is the receiver. No, I tell them, for it wouldn’t be failing on all four boxes. Then they think a satellite positioning or dish problem. No, I tell them, for then it wouldn’t affect only those four channels. They are sending someone out having someone call us to make an appointment to come out, but I don’t think that’s the problem.

Does anyone have a clue as to why only four channels would go out?

Update @ 10:00am PDT: Seems to be working now. Perhaps they were aware of the problem and just didn’t admit it. Still, grrrr….
