The confusion is because you didn't specify clearly what you were expecting to recieve the channels on (VM, SKYSAT, FTA, FREESAT) remembering that SKY channels are available on VM
If you're using satellite then it's a simple matter to check on this site to see if the channel is FREE or encrypted.

Any channel with an F in a square on it should be recievable via FTA (though if not part of a sky package you might have to manually tune the box via the engineers menu)
