Thanks very much for the info! Who do you think I should contact about getting a new box?
Could you tell me how old your sammy is please? or maybe when they started coming out? I can't find much on them

The SA 4200DVB that I have seems to be made in 2006 but i'm pretty sure they date back to 2004.
On a lighter note, I watched some missed TV using the catchup service, its brilliant when it gets going!
