Just had a TBox installed and now find that whereas before we got a full screen TV picture, we now get reduced
size pictures on some channels. We didn't have this problem with the old Digital Cable Decoder. Telestra "Help" said that the aspect ratio is normally on 16x9 but I could try 4x3. This cuts off the top and bottom of the picture rather than each sides with the 16x9 ratio. Can this problem be rectified or are we stuck with it please.?
