Controling border size in an swf within my website

When I import an swf into my website, I get all the junk that your not supposed to see. I didn’t know if there was a way to control that when I import it. So thew viewer can only see the swf how I see it in my flash player. Or is there a way to control the size of the empty movie clip that I’m importing the swf in? Wow, thats kinda confusing, sorry. If you more info on what I’m trying to say let me know.
Thanks!
