Simple answer is that you cannot. Older shows in particular classic t.v., vhs, and older DVD discs are presented in full screen. That refers to an older almost square in shape television set, and this format of the show is filmed or edited to fit that standard. New t.v.sets are predominantly made in standard wide screen (like the set in question). New t.v. shows, widescreen labeled dvd's and blu ray offer shows filmed or edited to fill the screen on the widescreen t.v. set. Therefore, to get full screen shows to fill the edges of a widescreen set, the image is zoomed (cuts off top and bottom of images), or the image is stretched (ultimately distorting and making images appear wider than meant to be viewed).
