Update:
So I decided to call the installer and get him to fix it. I called his extension after 8pm, expecting to leave a voice mail, but it rang through to somebody else and I explained my problem. He had the installer call me within 15 minutes. I hope the guy doesn't get in trouble.
Anyway, he told me that the Dish he used is new and he didn't have his software updated correctly so it was hit and miss whether it would work, but the software should update overnight and should be an easy fix when he came over today. So I think he's full of bs.
Here's the kicker. I said, let me ask my wife if she'll be around. He said, don't worry about it -- I won't need access to your receiver. I can just fix it by realigning the dish. This causes me some concerns and leads to my next questions.
--Doesn't he need access to the receiver to ensure he gets the best reception possible?
--If the dish gets pointed to 77, will the receiver automatically find the satellite and add the channels to the guide, ect. without the installer changing any of the settings?
I'm half tempted to just ask them to send out somebody else, but I don't want to cause this guy to lose his job or anything.
