I just got skyvisions newest catalogue, and they are offering digital package of 4dtv on ku-x4. looks like some channels i might be interested in. What is the miminum i would need to get set up to pick them up? I am already watching ku mpeg free 2 air all over the sky. I do not want a bud, or anything else on c-band and was wondering if anyone knows of a receiver that does both mpeg and 4dtv? I have a pansat 3500s receiver coming to upgrade my system. Any suggestions?
