I've been a Directv user since 1996. I tried to install Dish once but they wouldn't install with my old R59 wiring so I stayed with D*. But now I keep reading statements in various video threads about how Dish is technically advanced over D*. Could anyone give me a list of tech advantages of Dish. Most interested in picture quality but other advantages would be good. I'm coming up on my 2 year contract so I am interested.
