I just recently moved into an apartment complex that uses a third party to deliver directv. The company claims they deliver hd signal, and there are two satellites on the roof. One is a slimline 5 and the other is an lnb i have never seen before. The feed goes into a splitter in the closet that distributes to all of the rooms in the apt. I have a sd d12 reciever and an hd hr21-700 reciever. They both show signal strength of 94+ on the odd transponders on the 101 and 119 but 0 on the even ones. I show no signal on any other satellites with my hr21. I was told to go in and switch the lnb setup on the sd reciever to stacked, and that fixed the problem for that reciever, but I cannot find that on my hr 21. What can I do to fix this? And also if i am only getting signal on the 101 and 119, would that give me an hd signal?
