I've read through the primer regarding letterbox and widescreen and original aspect ratio, but I still don't have a good grasp on it. I bought a 36" Toshiba HDTV recently (3:4 right?). I choose it over a widescreen because for now we watch more TV than DVD and since I don't get HD televison right now (and the lack of channels putting out HD), I don't want the "bars" on the side of TV watching. I realize this means "bars" on the tops of many movies. My question is, what should my TV pic size be set to? I have three choices, Normal, Letterbox, and Compression. If I choose letterbox, I get gray "bars" above smaller black "bars". So I normally use compression, but aside from the bars, I'm not sure I know what the difference is. I've been buying all my DVDs in Widescreen...should I be doing this? And if so, what pic size is appropriate for watching these movies?
