I have a 501 PVR and an 801 HD reciever installed. When I discovered that Dish was adding Voom channels to the 61.5 bird, I checked to see if my system could see that. I am told that 9416, 9417, and 9418 PI channels are on the 61.5 bird. Is there a reason that my 501 can see those channels, but the 801 can not? The two recievers are connected to the same dishes on the roof of the house.
