Was curious, is the pin code when you 'lock' channels specific to the card, or the myskybox?   Given the mysky card has a microchip I was wondering if the pin number was stored on the card. 

I have a pin code for R rated programs set, so the kids can't watch them . 

I use the same sky card at our bach in a Skybox F5s settop box, but sometimes the channels don't show. Was wondering if that is because of the pin lock but that would mean the pin is stored inside the sky card as opposed to the device.. 

The Skybox has no function to request pin codes so I'm guessing this might be the problem.
