Hi camheidi,
you can find full details in the readme.txt file in the Predator folder:
Important: in order for the Sky UK NDS premium channels to work you
need to (apart from subscribing that is..):
-Tell your Dragon the serial number of the original Sky box your card is married to.
You can find this 10-digit number in the menu of your original Sky box,
services->system setup->system details.
You need the SERIAL NUMBER (and NOT the viewing card number!)
Now go to the menu of you Dragon, settings->NDS Box serial.
Here, enter the 10 digit serial number including any leading zeroes.
If your NDS card was already inserted into the Dragon, remove and
re-insert it after changing the Box Serial.
Now you're all set!
Failure to set the box serial will result in movie channels and other premium channels not
opening.
Best wishes
Mickha
