I have teh Panasonic RP91 hooked up to a 16x9 set. I have what I think is the 4x3 mode set to auto. I believe this allows the unit to properly display non-anamorphic DVDs through the progressive out. Otherwise, they are squished. However, the DVD player menus and the DVD Screen (e.g. when there is no disc in the player) show with black bars on the left and right. Is this correct? If I set the 4x3 mode to normal, the player menu and DVD screen fill the display, but then the non-anamorphic DVDs are squished. Am I doing something wrong?
