Well, I cannot say you are wrong because I'm not even close to be an expert into this issue.
I just say that "impossible" is a very strong word... I prefer to think it as "hard"... but, as I told above, I am not an expert!
Well, yes impossible a strong word but for joe average with $100 receiver he got no chance.
Hard, might be better but for hard, joe average need MediaKind RX8200 receiver or like that, activated with biss2 algorithm, loaded with exact biss2 xml file for decrypt that feed, MediaKind RX8200 need to be in ebu database for that exact feed and joe average need to be given xml file for that exact feed by ebu.
what chance joe average got, hard or impossible ?
