I have the most upto date bt vision box and have an 18 month bt broadband contract and the bt vision 1 and 2 are on my bt vision box but advise I need a viewing card to view. This contradicts the 'you must have infinity to view on tv' theory listed on bt website. Would I be able to view from normal broadband with a viewing card? I used to have setanta on my old box but don't think I have that card any longer. How do I get a viewing card, does it cost anything?
