For both of you guys- you need a 2nd LNB to be able to tune in channels from 82. "82" is another spacecraft up in the sky, so your dish has to be aimed to see both of the "birds."
Examples 3&4 from this thread will give you an idea of what I am talking about.
Bell can sell you an upgrade kit, or you get one when you buy a 6120 or a 9200/9220 receiver.
You can scan the satillite with a "Free to Air" system. For pay services such as Bell, it only allows you to see the channel names & number (but lets you see channels hidden to customers. What's currently being shown on those channels? no one know, only a Bell techician could see it as they fine tune the channel as they get it ready for launch.
Ya but the one that is there now it not the official nimiq 4, it is just a rented satelite for a little while. They will be launching a whole new one in one or 2 years.
