This may be a dumb question. I searched and didn't find anything, but I may not have been searching for the right terms. Learning about new things is interesting to me though. Can you get HD from DirecTV with a non SWM dish? Such as a regular SL5 or SL3? You can't get as many tuners on those, but if you only need 2 or 3 tuners, would they work and receive HD?
