Full browser Flash site doc type issue

I have to launch a full browser Flash site tonight, all is working great except one issue. The doc type which should be a validated working doc type (below) is throwing my whole flash to the top of the page leaving about 80% of the page all white:

<html xmlns="http://www.w3.org/1999/xhtml">

But if I use an outdated doc type (below), it works just fine and fills the browser fluidly as it should. I need it to validate, what am I doing wrong?
