I'm about to take delivery on a Samsung DLP 61," and the helpful salesman at Magnolia told me something I didn't quite understand: Sure, DVDs and HDTV signals fill (or almost fill, depending on DVD aspect ratio) the 16:9 screen. But what about broadcast letterbox movies/shows (Turner Classic Movies, for instance)? I assumed that these programs on my new 16:9 screen would still be letterboxed within the 4:3 box, thus giving black bars on BOTH the sides AND the top & bottom. What the sales tech assured me was that these letterboxed programs would be "blown up," (i.e, fill the screen a la a DVD with only black bars top and bottom) and thus look great on my new TV. Is this true? If so, how will there NOT be a falloff in image quality because of this enlargement of the broadcast (whether cable or dish) signal? Thanks in advance for the expertise! - Tom P. S. And feel free to tell me if this isn't the best forum for this question. I did look, and this seemed to be the appropriate one--but I could be wrong!
