You are correct, both Nagra 2 and 3 are illegal to decrypt.
the ones that says mpeg2 or mpeg4 is basically the way its transmitted to your receiver, it can be encrypted or not.
on lyngsat each channel on each satellite will have a highlighted color, which is a creamish color and have a F icon which indicates FTA channels. here is the link http://www.lyngsat.com/freetv/United-States.html
and you are correct, http://www.dishchannelchart.com is just a listing of all the channels from the american provider dish network which is a paid network. you can visit http://www.dishnetwork.com for more info about the provider.

Which channels can I expect to view legally from the satellites listed there? I take it Nagra 2 and 3 are not legal to decrypt. What about DVB? Is that free? What about ones listed as mpeg2 etc?
The http://www.dishchannelchart.com/ site looks good, however are these channels part of a package you buy from people like Bell? Or are all these channels free?
