I have no idea, why you can open JSC HD2 and not HD1 on Nilesat. We never advertised HD channels from AlJazeera. As soon as i remember, for the whole cardsharing.cc history, we always offerred only JSC channels from Hortbird.
Maybe, at the moment, JSC HD2 is opened - sometimes it happens with some popular channels with the purpose of ADV.
