The only problem is that 40 of the channels will be sports channels for different parts of the country. So you still will only get about (30) thirty true HD channels.
Depends on what you mean. I can get those 40 HD channels if I subscribe to the sports pack. And I will benefit from local replays of sports in HD, some news programs in HD, and over time, even more studios in HD. And all the while I will get much better quality and clarity for the SD content on those channels.
So for me... it is 70 channels. I can sit here and complain that he is counting HBO and Showtime which I don't subscribe to - but I don't/won't.
Look - 70-80-90-100 HD channels are HD channels. If he's counting channels you CAN'T receive or subscribe to you have a valid complaint. If he's counting channels you CHOSE to not subscribe to they are still channels.
