Hey guys, I just bought a 42" plasma and am considering upgrading to HD. Ive been a Dish customer for seven years and currently my only setup is/has been a 4900 receiver hooked up to one SD TV. I have a legacy Dish 500 with a dual lnb connected with a SW21 and a legacy 18" dish pointed to 61.5 for international programming. I am considering purchasing either the 211 receiver or 811 receiver on ebay to connect to the new plasma. I have already run coax from the roof into the room where the plasma will be and my question is regarding the equipment I will need to make this work. I did some research on this site, and it seems that I should be able to use my legacy equipment, but I am confused as to what new switches I will need and how to wire them. I still want to keep the 4900 reciever hooked up to the old TV, but I will now be adding this second receiver. Also, during my research I came across a few posts stating that hd receivers wont be activated unless the hdpack is purchased; is this true? If I decided not to get HD programming right away, but still bought the HD receiver on ebay, would they not allow me to activate but run standard def. programming? I appreciate all of your help in this confusing matter. Thanks!
