unfortunately I can confirm, the channels are not decoded "without any reason" (other channels work fine)
so server-admin might need to take some money in his hand (German expression) and get a capable Oscam server version on your own
I mean, as we all can see: it is possible to decode the "next layer of encryption" (don't know if it is named overcrypt key): DAZN 1+2 (which have also stoped working for some weeks) are best channels to show it: "usual SkyDE channels" (not using "overcrypt") are decoded within ~150ms each codeword. Switching to DAZN (1 or 2) and the times double to around 300-350ms (that's where it starts to get freeze at least above 450ms response time for every "7 seconds valid codeword"). Simple reason: this channel is bought from an external source. And of course it doubles the time to decode as the codeword is send from my receiver to cs-server > from cs-server to external cs-server > and the same way back
And I am thinking about new channel request for Sky One (or Sky 1 DE) as it should also be possible to get Sky One the same way as the DAZN channels (which many freezers, as already explained).
My subscription (and most of my friends) ends at the beginning of next year. Lets see how admin reacts or I switch to another cs-server. Because it is possible to decode, it only requires a "non public Oscam version" at the server - and as we can see with DAZN: ONLY the server requires this expensive Oscam version, the clients are fine with the cost free Oscam (or other emulator).
So if you are looking for another server: get one who offers DAZN channels and Sky One (and the channels listed in the posting above) and check the response times: if time for "overcrypt channels" is much higher look for another server.
