Foxy Fierenza

I have a "free" freeview Tv i picked up and after some messing about managed to get it to work ok, BUT now when it shows say a you tube article the content of whats been shown also appears over the inside of the house ceiling and also over all the furnature in the TV room?? Any one heard of this sort of thing happening before please as i cant seem to fix it? Im using the SL viewer 2 Many thanks for any help Foxy :)
