I recently moved into an apartment building that deals w/ a DirecTV third part, Discernity, and am in a bit of a complicated situation and looking for suggestions. My roommate lived in the building before, in a different apartment. We were able to plug his DirecTV box in at the new place and it seemed to work just fine. That was only an SD box, so we ordered an HD box directly from DirecTV to add-on. Now we have the box and we are trying to install it, ideally without paying Discernity to do it. Is this possible? Right now I'm going through the different satellites and have been able to get SD signal through the box but not HD? Any idea what I need to do? Is there any information I can pull off of the other box that would help? Are the SD and HD signals on different satellites? Thanks guys.
