there is soemthing they need to update though when they install it which they won't tell you how to do over the phone
someone like smudge should be able to let you into the secret though, plus the codin of the box to the card and that's all it is
i did it myself and the lady o the phone as asking all sorts of questions as to what i was going to do, where i'd got it from, how much i'd paid for it unti i told her it was none of her business and she was supposed to tell me why it wasn't working
then she got all shirty and said i couldn't use the old card in the new box and they were going to charge me £20 for the upgrade so i said i wouldn't bother then and just keep the package i was on
so what i did get was the upgrade to hd, plus multiroom (the old box went upstairs) and a new card and a new contract to replace the old one which had expired
the only thing i didn't get was the warranty as i bought the box second hand off of westy, but you still have to sign up to a 12 month "you have to plug the phone line in and pay for the hd subs" malarky
