I have a Panasonic TU-CT20 Freeview box connected to a 4:3 CRT in my bedroom. The box ix set for 4:3 picture and has worked very well with BBC1,2,3,4 and ITV etc. Since ITV 3, 4 and C4 came onstream it seems incapable of giving a proper 4:3 picture on those channels when they are transmitting a widescreen broadcast. The picture appears in its anamorphic state and also has a 'frame' around it as well. The box continues to convert other channels OK. Any clues, or is this a fault of the broadcasters?
