aligning the background image with a .swf header

[bongodog]

this is probably an easy task for someone who knows what they're doing... i'm a noob at web design so could use some advice.

having trouble getting the BG image to align with the Flash header...

when i try this code:

background-position: center center

the BG image is centered horizontally but crammed up top underneath the header

so i tired this:

background-position: horizontal center

and oddly - the BG image is moved down the appropriate amount - but now is aligned on the left and not centered horizontally at all...

what gives?

adding the following line changes nothing:

background-position: vertical center

here is the page as it currently looks:

I appreciate any input...
Cheers!
