No way to check this until Genpix fixes their turbo qpsk issue, but I'm wondering whether DN thinks that they have fulfilled their obligation by having it FTA on the 77 sat? Ie before that switched to turbo qpsk, it was fta there also. Maybe it's still FTA there?
But I really think that they have just done a major shift of all their channels, and while at it, just happened to turn all the encryption on. If that's the case, the 3 or 4 channels I'm still seeing FTA on other sats will probably encrypt too, as soon as they get to those sats.
