That's not what two LNBs do. Two LNBs *see* two satellites at the same time. What you are talking about is a "dual" LNB; i.e., one LNB with two outputs at the bottom...one goes to one receiver, the other goes to another receiver. You can have a dish that has two LNBs, both of which are dual.
I'm not sure, however, why you have a dish with two LNBs for DirecTV. DirecTV SD programming uses only one satellite (101) and DirecTV HD programming uses 3 LNBs.
