Last night while I was watching ESPN I noticed small pixels or artifacts in the scroll in the bottom of my TV is that normal for a Samsung LED DLP or do I need a tech to come out to fix the problem. Also does anyone know if you can play HD DVD or Blu Ray in 1080p 24fps because when I select that option the screen shakes and stays that way until I choose 1080p. The connection I use for all my equipment is HDMI.
