Logo align SWFObject

[plienine]

Hello,

I am using flash player for my videos displays, and have one problem:
Logo displays on right-top corner, but I want to align in right-bottom corner .
What code do I need to add?

My code now:

so.addVariable('backcolor','0x000000');
so.addVariable('logo','http://pornofanatic.com/images/flvlogo.gif');


However, I tryed to use logoX and logoY but it doesn work,.....
