when i play a divx or xvid file the displayed image is very small(about half the screen)with large black bars top and bottom ,ive got the player set to output 16.9,my old pioneer 585a would display the same files but the screen would be filled or at the most small bars top and bottom,am i doing something wrong or is this just the way the player displays these files?,ived tryed the zoom feature but basicly that is just magnifying the image rather than expanding it to fit screen.
