I got a Cyfra+ Nagravision card, as well as correct config from the seller. It's weird that it opens TVP channels, Eurosport 1 HD, but not Eurosport 2 HD. Eleven sports channels also stay black. Oscam is cak7-patched 11615.
Log sample after changing channel to Eurosport 2:

Does this mean that the packet is incomplete on the card, or some misconfiguration?
