My father had a new dish installed today since he has now joined the HD world. I have not been over to check out the installation but he is unable to receive some channels. I asked him if it was a single coax or dual going into the receiver. He said there where two. He has an HR23. He gets 207 but not 206. He gets 247 but not 245. He also says when he goes to the music channels (237 as an example) it says he has to pay for it. It never said that before. Does this sound like an authorization issue?
