This makes no sense to me on direct tv's part to not integrate an ota tuner into their hd recievers. First of all I wouldn't think it would be a cost issue. Does anyone know why? Is it because they want to force people to except hd locals if available? This truely sucks for me. I am in a market without sd or hd locals even though Lubbock, Tx is a fairly large market considering it provides locals for most of west texas. So I have to either get cable, dish, or pray that the am21 works. Because yes my tv is old enough that it does not have a atsc tuner. Any explaination would be great.
