Hello all. I just bought a Panasonic Plasma Widescreen. The picture looks great, but I have one gripe. Widescreen DVD's still have black bars on the top and bottom of the screen. I thought the whole purpose of getting a WS TV was to avoid this. Why does this happen, and is there a way to fix it? (Zooming gets rid of the bars but causes distortion) Any thoughts? Jeff M.
