I recently purchased the HLR-4266W and I am noticing issues with very dark scenes in movies and shows. The problem I have is when there is movement in dark scenes, the dark areas get very block like (not really sure how to describe it other than that). The image transition as the camera moves is not smooth at all. Is this something that can be fixed with the TVs settings? Is it the component cables that comcast provided? I noticed this happening while watching both a digital movie and an HD show on HBO. Please help, I am running out of time to return the set if there's no way to fix this.
