Is this dithering I am seing on fast camera pans rainbows? Or is this the screen door effect? I have a Toshiba dlp 52hm84 and love the picture on this set, except for this dithering type thing that happens during camera pans or a quick turn of the face. I notice this dithering most in the face of the person on screen when I get a camera pan. Is this normal for the dlp technology? I can live with it because it seems all the projection technologies have their hickups. Is my set defective or is this normal?
