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.

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.


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

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?

No, and you proved that.


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

No, it won't do what you describe.
