I currently have Dish 500 with one 625 and three 301's(all leased). I was thinking about upgrading to HD. My HD locals are only on 77 and from my understanding only supports VIP series of receivers. I am trying to prepare myself with what to expect when I call Dish customer service to see what they will upgrade my equipment to. Am i correct to assume that their only upgrade scenario would be to upgrade me to Eastern Arc and replace all my receivers with the VIP line?
