Hi Gonk, Thanks for the informative reply. The box I have is a magnovox TB900 somthing. It has 3 ratio settings "full screen" which gives me black bars on the sides not the top or bottom. "Zoom" which gets rid of the bars but is to much when the picture is 16:9 and "letterbox" wich gives me bars top and bottom at all times. Ive been sticking with "zoom" to tell the truth. Its pretty easy to see the picture is wrong when a full HD widescreen picture comes up so I just have to switch alot or forget it.
