Every DVD I play in the Philips Q50 looks fantastic, but Lawrence of Arabia strangely has a lot of flaws. Occasionally I see a large but faint white vertical bar moving around the center of the screen. In desert scenes, the sands have a flickering effect, and I can see faint black "smudges" flickering on and off. Its weird. Is this a problem with my particular disc or are these problems due to the age of the source material? I doubt the problem lies with my system because none of my other dvds exhibit these artifacts.
