How much difference between SD and HD
We can't find a carry-out antenna that will support DirecTV HD. How much difference is there in the clarity between SD and HD?

So it sounds like we have to learn how to aim our dish, huh? How do we know if the TV has an ATSC digital tuner? Will it say so in the instruction book for the TV? We have a Vizio...2 years old, I think.
