Thanks for the replies! Unfortunately, I'm the last person on earth without a digital camera. However, I can say that the setup seems to look similar to what you described, Charper. The "main" LNB looks like a conventional dual configuration. The other one is much smaller and has an odd looking plastic cover over it -- different that your pictures. It kind of sticks out and is marked something like "Ka/Ku." But I don't see anything that looks like a fifth LNB, unless it's unclearly hidden in the smaller unit.
Runing the diagnostic during installation, it indicated that there was failure of the 5 LNB installation -- and that 99 degrees was missing. There were two installers present today; both saw this and said there was no problem and that this was normal.
Hours after they left, I was playing around and noticed that I didn't see any active transponders on 103, either. I didn't run through the whole check, but I was curious about the fact that I wasn't seeing my locals in their regular OTA spots via spotbeamed MPEG-4 -- which I saw on Lyngsat, is where LA locals would be on that bird. Of course, I was getting my locals in both SD and HD from the CONUS satellite. So I'm worried about 103, too.
I'm very savvy with Dishnetwork (and Expressvu), but this whole Directv is a new ballgame for me.
Thanks again for your insights, especially if this is something I should worry about.
