Hello suma,
of course I am aware that you might not be able to receive Astra-1 channels and HD+ services at your location and that you have to use the information you got. I would also understand if you or the server-admin claim, that the number of cards you are using at the server would not cover more than the normal HD-channels of HD+, I have no experience but of course you can only decode a limited number of different channels with one (or even 2 or 3) card before customers experience freezers.
However, I only claimed, that UHD channels on HD-plus do not require a "special subscription" by now the channels are available for all HD+ subscribers - and obviously as the channels are working now, I am right with this statement. Even if I am not able to receive UHD channels because if my limited equipment I want to thank you and the admin for adding the UHD channels of HD-plus to the server.
