Heyas, just got my new set today but I am a bit put off by something I noticed. Through either component or via HDMI widescreen DVDs run with a box at top and bottom on my set via the SD-5970 Toshiba DVD player. The output is set to 16:9 and I thought I wouldn't get this, but I do. The image is perfect, but with boxing. Is this normal; if not, what do I change or look for?
