It looks correct to me now - before the images weren't extending to the full width of the slideshow as they were set to have a max-width of 97%, and 7px margin (if I remember correctly). If you're referring to the fact that the footer is wider than the slideshow, and the slideshow is wider than the header, then that's a problem with your theme CSS rather than Meta Slider - you'll need to tweak your column widths so that they all line up.
Edit, just taken a close look at your theme; Remember that a container which is 1000px wide, with 10px padding on the left and right, will render as 1020px wide in total. If you're not using FireBug or Chrome Developer tools to help with your CSS editing then I strongly advise taking a look at one of them, they're simple to use and make your life even simpler :)
