Cleaning a movie dvd

[ms]

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?

A 'used' movie DVD? 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.

You are describing a DVD made from a *bad* print of the movie, one
that had little or no cleanup and fixup after transcribing. Not
uncommon for low budget transcriptions to DVD.

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.

No, and you proved that.

And, is a dirty dvd the problem in the above results?

No, it won't do what you describe.

Macrovision funnies? How is your TV connected to the DVD player? Is the
DVD an original or something someone has knocked off from another source?

Listen to what they are saying. 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.

Thanks to all. I should have mentioned, this is a commercial DVD, the
garage seller bought new, the dvd has the expected label side. So IMO
it' original.

I will try distilled water as a wash.

And to think. these baby rapers have the audacity to call me - the

Some counterfeit DVDs and real ones can look quite similar side by side.

Forget the wash - that will not fix the symptoms.

I repeat, how is your DVD player connected to the TV?

It's connected to the TV the same way that everybody elses DVD player
is connected to the tv through the two screws that say UHF in the back
of the tv.

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.

You're kidding. Virtually everyone connects their DVD through a direct vide
input.

What the **** is a "vide" input. You mean a Video input?

What if your television doesn't have one like half the televisions
made?

Then where the **** do you stick your fucking dvd player?

You hook it up to RF modulator and you hook the output from that to a VHF
input, not UHF like you said, you gush craving bitch.

Call me what you want to, at least I am not a recreational cat killer.

Yes, it paid off to do my own Googling.

In fact, what DVD players have RF output?

Thanks for answering the troll. Now the chance of this thread going
anywhere to help the OP is zero....

 

[bz]

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.

my Samsung VHS/DVD 5500 has RF output. I just looked at the back of mine.

Yeah, the fact that he's an uneducated motherfucker and a pseudotroll

A lot of high end teevees had inputs but at that time a lot of cheap
motherfuckers didn't.

I think you identified the problem. I cleaned the DVD with distilled
wster, so after air dry it was again unblemished appearance.

There is nothing wrong with the small TV monitor, or the connections as
it plays other movie dvd's fine. As in my OP, I was playing a dvd, not
using a VCR tape recorded copy or anything else.

After washing, the movie looks the same, from the opening credits screen.
the movie is alternately light and darker. The initial 20th Cen. Fox
video and no copy screens are perfectly stable, only every movie screen
is a problem.

This is the usual commercial dvd, "20th Cent Studio Classics, etc. ".

But the film quality sure looks just as you described.

A comment on above?

Thanks
