Page Background Questions

I am trying to create a similar effect in my background as this website (not the design but the whole background appears to be in flash, page opens centered horizontally, and there is no horizontal scroll bar):

I made my background 1280x1024 and placed it into my flash page and made the flash site the same size (1280x1024). So then in the html I made a table with one column and one row and centered my flash object within this table. The problem is when I open my html page the page opens all the way to the upper left of the page not horizontally centered and there is a horizontal scroll bar.

Is there a way to have my html page open horizontally centered and have no horizontal scroll bar?

Thanks for the help,
Brian
