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
You can view any channels which are available to you with your current Sky subscription card and box id number has to match the one paired with your card, your card must of course be inserted in the CAM.
