request assistance - unwanted embedded...

Hi there.

So I have a flash intro, which shows as I want it to in Firefox and Opera...as the flash player in the center of the screen. However, in internet explorer, it shows up with ugly scrollbars (not the browser scrollbars...scrollbars within the embedded object region). How do I get rid of these without messing up appearance in the other browsers. For reference, I am using Yahoo Site Builder, which I know is a big no no, but it's where my ability is at right now. Below is the code. I am sure it is messy, but please let me know if there any major problems with it and how to fix this. Thanks.
