You have space left over on each side when you put the shape of a standard def program on the screen. You can always stretch or zoom, but that's your preference. I would keep it as it is and see the original content the way it was meant to be viewed. Standard-def channels have a 4:3 aspect ratio; the width is 4/3 = 1.333 times longer than the height. High-def channels have a 16:9 aspect ratio; the width is 16/9 = 1.78 times longer than the height. If you take a standard def image (1.33:1) and put it in a widescreen set as large as it will fit, you will have black bars on the left and right. It used to be that all programs (movies and television) had a 4:3 apsect ratio. When television was introduced, the theatres had to have something novel to draw audiences back to the theatre. They switched to even larger aspect rations of 1.85:1 or 2.35:1 (width is 2.35 times longer than the height). Early movies like "Gone with the Wind" the original "Dracula" and even "The Wizard of Oz" were all 1.33:1 and would fit perfectly on standard def screens. Since a lot of movies have even wider screens than HDTV's, you are going to even run into black bars on the top and bottom. 16:9 (1.78:1) is basically a compromise between standard def (1.33:1) and theater (2.35:1).
