moire effect

Uh, not sure what you're talking about.

This is a Moire pattern:

To qoute: "When a transparent pattern lays over a second pattern, the combined patterns are called a Moiré .

"The word Moiré was first used by weavers and comes from the word mohair, a kind of cloth made from the fine hair of an Angora goat. Artists hate moiré patterns because they can sometimes ruin a printed photo or drawing. But they can also be great fun.

"Moving one pattern over another can generate fascinating visual effects. These exhibits represent a small sample of the astounding variety of moiré patterns possible."

I don't see what the issue is with audio?

something to do with screens that allow the center chanel to be behind them & the pj having a strange look to it....................?

If the screen is moved by the output of the center which will result in the moire effect being visable under certain conditions, then you can do 1 of 3 things (that I know of):

1) get a more acoustically transparent screen

2) move the center to either above of below the screen

3) break up the output by using multiple smaller speakers as center speakers distributed so that they do not alter the shape of the screen surface

That's all you can do...

It can be a problem with the dot pattern of a video projector being projected onto a screen that has some type of open weave or that is a perforated material. You won't know until you try it as it depends partly on the size of the dots and size of the holes in the screen and where they line up.
