DISHCOMM, thanks for responding, but please keep in mind the following two facts:
1. On Friday, I was in DMA X (HD locals), and on Saturday, when I removed the 721 and added the 622, I was in DMA Y (no HD locals). According to the DMA map, I am definitely in DMA X, even though most of my zip code is in DMA Y. If DMA's are determined strictly by zip code, then why do DMA maps exist? The map I looked at puts me in DMA X (HD locals).
2. And this is the important one. According to Dish I am in DMA Y (no HD locals), and according to DirecTV I am in DMA X (HD locals). If, as you say, AC Neilsen determines a location's DMA, then Dish and DirecTV should be using the same criteria, and both would place me in the same DMA. In my case, Dish and DirecTV contradict each other, so someone is using incorrect data or processing the data incorrectly.
Regardless of X, Y, Z, LSMFT ... I currently have HD locals, although I had to lie in order to get them, and I hope that I never need onsite service, because then I will have to move from the phony address and then, after the service, move back to a phony address.
Receiving HD locals should not be this difficult.
It seems obvious that the process of assigning people to specific DMA's can be problematic and needs to be addressed.
Just my thoughts.
