I've seen this questions asked many times but received so many different answers that I thought I'd ask a specific questions based off of it.

What HD channels have you actually seen and know it is broadcast through the satellite without the use of any special antennas?

For instance, I know that I have seen HBO broadcast in HD for DirecTV and I know that I have seen a "DEMO HD" channel. all fo the other channels that I've heard is HD capable, I have not personally seen. I hear that there are some PPV channels but dont know for sure. I also hear that the local channels will work only with a special Antenna but haven't see that either.
