Nelson,
not 100% sure about all this but I think you will find that you'll have to get an AFRTS satellite and decoder if you want anything in English, except maybe Eurosport. And they, as of now, do not broadcast any HD. Your NTSC will work with AFRTS as they broadcast in that system but will not work with any Euro systems. Also, if you have DVDs, take a look on the back of a package and you'll see a region stated (usually in the boxes toward the bottom of back cover). You should see region 1, which is North America. Local rentals over there will not work on your NTSC TV either. Many DVD players are multi-region but it has to match the TV.
http://www.afrts.osd.mil/ may provide more info. It'll also give you a look at the programming on AFN.
Hope all that makes sense.
