Cleaning a movie dvd
The used movie dvd looked IMO clean, no scratches, very clean, even viewed
at a angle, could see nothing. I played it and got, I believe, an unusual problem. A scene in a lighted room, the lighting is bright as you would expect, but a moment later, the lighting dims, then brightens again. This repeated at random intervals during the viewing. The movie was "The Man in the Grey Flannel Suit", and that was not in the movie. I replaced it with another movie dvd, it played fine. I washed the problem dvd in plain water, let it air dry. Now it has water spots. Haven't tried to play it again. What is a safe way to clean a movie dvd at home? And, is a dirty dvd the problem in the above results? ms |

Could it be a bootleg DVD? Some protection schemes cause brightness variations. For example, if you play a DVD back and try to record it on a VCR or play through a VCR, you will see the brightness cycling from dark to viewable. As for cleaning the DVD, washing it with clean, deionized water and letting it air dry should work. NO scrubbing!!!!! 'Scrubbing' can drag abrasive particles across the optical surface of the disk and scratch the surface. Window cleaner and lens cleaning tissue, properly used (one pass only, no pressure) over the surface can work also. -- bz 73 de N5BZ k please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set. remove ch100-5 to avoid spam trap |

The movie was "The Man in the Grey Flannel Suit", and that was not in the movie. But it was in the print the DVD was made from. Bet your bottom dollar on that.

A DVD is a digital media. Dirt may cause drop-outs, noise, pixellation, jumping or skipping frames or more, or even lock up the player. It isn't likely to produce variations in scene brightness. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

I will try distilled water as a wash. ms There is no need for distilled water, nor any need to be particularly careful. Any fingermarked CD or DVD can be cleaned with ordinary washing up liquid, worked across the disc (not around the disc as has been pointed out by others) by your two thumbs. When you have been over the whole disc in thus manner, rinse it off with warm flowing bog-standard tap water. Shake the excess off, and then dry off the remainder with a dry lint-free cloth. Minor lower surface scratches are of no consequence whatsoever. The error correction systems that are employed, are more than adequate to cope with such minor imperfections. I would agree with others that have posted answers. The disc in question was almost certainly mastered from a bad print of the original film. A dirty, scratched or otherwise damaged disc, will not cause any 'analogue' effects of the type you are describing. Arfa |

You're kidding. Virtually everyone connects their DVD
through a direct video input. In fact, what DVD players have RF output? I checked a Sony DVP-S7000 (one of the first, if not the first, DVD players). It has no RF output. At the time DVD players were introduced, many TVs had direct inputs. I don't know what percentage of DVD players have or had modulators. |

"The Man in the Gray Flannel Suit" is a virtually forgotten film, most
memorable for a scene in which Bernard Herrmann shows what a brilliant composer he was. In a few seconds, the music reveals everything going through Gregory Peck's mind. The question is... Who would _want_ to pirate "The Man in the Gray Flannel Suit"? |
