Anyone know where/how the HD NBC network feeds work on satellite? I currently use a Tiernan TDR6 4:2:2 decoder and 1 M Ku dish aimed at AMC-1 for the SD direct network feeds but wonder just what equipment would be required to receive the same network HD feeds - especially since the SD feeds will be gone in Feb 09 I would think. Same satellite, different transponder? Format? I know that Tiernan offers an HD plug-in for the decoder but $3K is a bit much. Thanks for any help guys.
