css help needed

[cyberdread]

I have a table with a flash movie inside, within a div on my html page. linked to the div (id-all) is a CSS external stylesheet with the code:
#all
{
width: 886px;
margin: 0 auto
}

this centres my flash movie on the middle of the page (horizontal)

the problem is: there is large gap of several pixels from the top to the flash movie where you can see the black background. And yes I checked table border=0 and cellpadding is also 0.

What CSS code do I add to keep the div in the centre but 0pixels from the top?

If you are using Dreamweaver it could be a cellspacing problem rather than cellpadding which you said you set to 0

no i use flash 5 to make the movies.
export movies, and write html page with notepad loadin the flash movies with code i write there.
