Hi everyone, i'm planning to upgrade my dish equip. and I was wondering if it was possible. Currently I have a 2700 and a 3700 receiver with the dish 500 legacy twin LNB. The system was originally installed in 1999 and was upgraded to dish 500 in about 2002/2003. However, only the LNB was changed. I want to upgrade to a four-room setup with two dish 322 receivers, and that requires a DishPro LNB. So, I have a few questions about this setup: A) Will the smartcards i'm using now work with the 322's? They're the newer orange ones. B) Do I have to call Dish to reactivate the receivers or whatnot? I'm planning on buying the receivers off of eBay. C) The legacy receivers (2700/3700) will not work with the DishPro LNB, correct? Thanks.
