Thats the problem with LCD technology. If your primary source of material is sports where you have a fast movement of the picture you don't want to use LCD. One of the criticisms of LCD TVs is that they sometimes can't keep up with motion, and a trail follows the image as it moves across the screen. New LCD displays like the Sharp's LC-45G1U wich has a refresh rate of less than 16 milliseconds is said to improve performance in action sequences.
Also I don't remember the size and model but RCA and Infocus were both displaying a DLP set at CEDIA that were identical and the one from RCA had the Infocus sign on the right front side.
