static images are murder on crt and plasma displays. Try to limit the use of static images (black bars, games with onscreen displays etc,) to about 15% of your viewing. Also it helps to reduce the contrast or white level down maybe 15%on your tv. They are almost always maxed to give off the brigest picture in stores. Unfortunately, panasonic or sony etc, dont know which tv the guys at best buy or circuit city etc. will unbox and put on display, so every tv is maxed out and this give you a washed out picture, reduces the life of the tv, and increase the chances of burn-in....
