I've heard some of the main networks are in HD via FTA. Examples I've read of people receiving are NBC, ABC, and CBS. As for WB or UPN, I haven't heard of those being received in HD. Of course you would need a $700 set-top receiver to receive these channels because normal FTA receivers can only decode those of 480 interlaced resolution and not HD resolution. They also cannot decode the type of color encoding that many HD channels carry which is done in a 4:2:2 color ratio. Normal FTA receivers can only decode video with a color encoding on a 4:2:0 ratio. You can purchase receivers for the computer that have HD capability, but they don't have any blindscan features. That means the computer receivers will not automatically program in all of the satellite information. You have to manually enter in the specifications for each channel (symbol rate, transponder number, polarity, etc.). From what I've heard, the $700.00 set-top receiver that has HD capability doesn't have blind scanning either. For more information, make a post on the FTA forums and some of the guys will be able to help you out more there.
