Dish VIP222 issues

[clj2]

I have a Dish VIP 222 reciever....it is for HD, but I don't subscribe to HD service. Was told a HD Dish was needed upon installation due to our location. Anyway, on the local channels, some of them (NBC, ABC, FOX, CBS) look 'boxed in', squeezed in to the middle of the screen. What is wrong? I fixed this on my second TV for this reciever but can't remember how so I can fix my other one. 3 or 4 of the locals just don't look right. How can I fix this? Upon installation I was told it was due to the fact that it was a HD reciever and I didn't have HD service and they were developing some "software" that would fix that. Any idea what's up?
