THE GUIDE POSTED BY JULIETTE SCHULTZ IS TOTAL RUBBISH! I HAVE BOUGHT AND SOLD LOADS OF CARDS AND FOUND THAT ANY CARD WILL WORK IN ANY BOX. ALL THE FREEVIEW CHANNELS WILL BE AVAILABLE BUT TO GET THE FILM PPV CHANNELS YOU MUST HAVE THE CARD MATCHED. IF THE CARD DOES NOT WORK IMMEDIATLY TRY LEAVING IT IN OVERNIGHT AS THIS IS WHEN THE SOFTWARE IS UPDATED. HAPPY VIEWING! CHEERS ENGINEER 9990
