Actually 110W provides only MPEG-2 "SD" channels to Puerto Rico. Along with System Info., control, authorization, and guide data to the island.According to the transponder maps over at DBSTalk they're still showing that DIRECTV5 at 110 is still being used, but for providing HD channels to Puerto Rico.
For PR only, 110W ...Where does their guide data come from if not 101 or 119?
SD only stuff likely will go MPEG4 SDSo are SD-only stations like Boomerang going to be upscaled to HD? Or will they remain in SD?
