We have Sky Deutschland card, not Austiasat. We don't care what is included in other packages, not from Germany. You were told that the channel cannot be added to the German subscription. Either, it is a 3rd party channel renting transponder, or it is PPV channel for SkyDe, or whatever. If you don't like my reply, you may address to the Moderator and you will hear the same words from him.
