The local stations are still broadcasting this way, but Dish users with normal (not HD) tuners are finding the picture cropped, obviously so, because credits, ad bugs and the like are cut off. So far, no one at Dish has been able or willing to explain why they started doing this and when they will go back to normal. I can't even verify if it's an Oregon phenomenon or national. The satellite/cable channels do not have this problem; if sent in 16x9 we see them in 16x9.
I'd love both an answer and a verification that this is happening to people around the country, and also if it is affecting DirectTV customers as well.
