I don't know what their doing at D* but something is going on. Yesterday they had a problem with channels 80 and 81, and it took numerous calls to get that corrected (a previous thread shows what was happening). The CSR kept saying it was my problem, then after being transferred to a 3rd tier technician they finally, at my urging, checked their own HD receiver and found they were having the same problem. Even when I told them another person on this forum had found the same problem they insisted that I reset my HD TiVo, and "I" had to tell them the signal strength of the two channels (both on the same transponder). One CSR told me I wasn't authorized to receive HD channels! I had to convince her I subscribed to the HD package. While I was on hold (for over an hour) with the technical rep I casually asked about TNT HD and was told, oh no, no new HD channels until the new satellites went up. But he was also the same person who told me Channel 80 and 83 were PPV channels (they were showing a PPV notice telling me to hit select if I wanted to get the movie.)
Edit: I note that the data now is correct on HDNet but for some reason that channel and Discover HD had been removed from my favorites list!
