I am late joining in on this thread. Take a look at http://www.ftalist.com if you want to see all the possible channels (in a much better layout than Lyngsat) that is available in North America. Lets you select by language, satellite and such.

With KU Band, only PBS is availble in HD. Otherwise you need to go to C-Band and much of that is encrpyted anyways. Only advantage to C-Band is that there are more locals out there available as unencrpyted for all to see.
