CharlotteB:I keep reading about people buying new SKY HD boxes, 'better' ones. Mine seems to work fine but IF I wanted to buy a better one is it as simple as just swapping boxes myself and sticking my new card in or what? Do I have to buy from sky??

Yes, it's that simple and no, you don't have to buy from Sky. I took Sky up on their offer last year of new HD boxes for £75. The offer was specifically for new customers but they did it for me. I got a new box which has coaxial (into my DAC for radio duty) and optical (into my receiver for 5.1) inputs rather than just optical and I sold my old one for £120 on ebay!
