Received the DCR lens today. Removed the Prismasonic and installed the DCR. Pretty easy installation, but expected that, since it is a fixed in place lens. With the auto aspect ratio control of the Lumagen and the DCR, I do not have to do anything. When a 16:9 movie or show is playing, I automaticlly get 16:9 image and when a scope movie starts playing, it fills my 2.40 aspect ratio screen. Works pretty slick.
