it looks like your page is putting jquery into compatibility mode:
//Tell jQuery not to take $
jQuery.noConflict();
//Create a short jQuery reference for convenience
$j = jQuery;
for the slideshow, but the menu is not using compatibility mode. both scripts will need to use compatibility mode, you can have one script using compatibility mode and the other not on the same page.
