Has anyone else noticed on some of the new HD Channels that whenever there is a dark scene or a not so well lit scene that colors start to look painted and almost a little cartoonish? Is this a side affect of MPEG-4? I have not seen this happening on my HD-DVD movies and they all use MPEG-4. I it because of the lower bitrate? Anyhow I have a 61" 1080p TV so maybe I just notice it more than some folks.
