[HELP]Works in IE but not others CSS Question

Hello-

I'm having a problem with positioning one element on my web site. It works fine in IE but Opera, Firefox, Mozilla, and Netscape all push the element to the left. I've tried just about everything I can think of and I'm hoping another set of eyes can see what I'm missing.

The site is http://design.dvdfuture.com/index.php When you go to it in IE it looks right any other browser and the feature review is off to the left. The CSS code is below. Thanks for any help.

Code:

/* every page */
body {
 text-align: center;
 background: #C1D8E2 url(../images/background3.jpg) repeat-x bottom fixed;
 background-color: #C1D8E2;
