Wolf,
What are you talking about. NFL Network has been in HD on DirecTV for a month now. Did you upgrade with the new dish requried for the new MPEG4 SAt?
Over 70 channels are now in HD, including Big Ten Network, NBA Channel, NHL Channel and 8 or so FOX Regionals and Comcast regionals as well as MSG. Also, if you like movies there's now MGM HD.
If you have the new sat you'll see 212 HD and 212 standard next to eachother in the grid. If you're receiver is setup properly it automatically goes to HD.
