Thanks. A couple of years back, when I tried to search for info about XTream Codes, Google refused to give me any useful information, other than links that say "EU cracking down" on it.
Now the water seems to be a little clearer (but not totally clear), I will look into this and see what I can do. Hopefully I will be able to search and find more technical information on it.
By the way, is it "XTream-Codes" or "XStream-Codes"? In the above-linked article, the title says "Xstream", but in the body of the article it is "Xtream" in multiple places.
