It appears that if i want to upgrade to HD with HD locals(Cincinnati), i will have to move to eastern arc. as i currently only have dish 500 for sd. I have a 625 and 3-301's..all leased. If Dish moves me to EA..will they replace all my receivers or will some of them work on EA? SOme of the EA info i have read on here has me confused...some say MPEG4 only receivers while new smart cards are mentioned with EA...
