Hello dudes!

I just updated my HDMU to 12212 and I'm having some problems. Let me describe my situation.
I have a triple LNB set up for the following positions:

19.2
23.3
28.2

My previous HDMU version (11... something) showed all of the channels in my channel list. The current version shows channels greyed out in the list saying " N/A" in grey. When i click on them it says check tuner config. So i dont know if i did that right.

It seems that a lot of the channels on the 28.2 are N/A. Especially the SKY UK channels. I watch those the most so this is a problem for me.

Does anyone know what the problem might be?
