I went to order the UFC PPV on tomorrow night and found an interesting contrast. When I try to order the HD PPV on channel 98, I get the "Please try again, or call customer service, ext. 741." error message. When I try to order the SD PPV on channel 123, it all works fine. Why would one work and not the other? Is this just a D* problem, or could there be something on my box causing it to be unhappy with one and happy with the other?
