I recently purchased a Toshiba SD-5700 DVD player and I am extremely happy with my purchase. However, just this past week I rented Titanic and had problems geting the picture to fill my Toshia 50HX81 widescreen format. I tried all options with the DVD player, as well as the Toshiba format choices, but could not find any way to have this picture fill my screen. Could this have been the DVD itself or am I missing something with either the player or TV? Any insight would be helpful.
