sharing of the new card works perfectly with newcs but you do need to block the GA in newcs.xml
if you have been daft enough to insert your new card into your sky box and it has becomes paired with the box you need to follow these instructions bellow.
Take serial number from official receiver.
Delete first two numbers.
Then that number use Hex - Dec converter
Then you have a new number
Add 0 to the start of that number
Add this new number to newcs.xml
<boxkey>********</boxkey>
enjoy.ian.
