I have been using a Zeatek decoder for a number of years with MySky card in another room in the house. Last week after using for a few days I took the Sky card back to the sky decoder and while I could watch Sky I could not record or play anything previously recorded. I rang Sky and they asked if I had used the card in another decoder. I said yes and they said they would have to reset the MySky box. Is this new? Will it happen every time I use the card in the Zeatek Box? Can I rest myself?
