Jquery incompatibility

In the same WP 3.4.2 page, we use WP Supersized and uniformjs.com implementation with http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js. The WP Supersized don’t load background images. We have try down until jquery 1.2.3 version and we have had the same problem. When we try with jquery 1.2.2 WP Supersized works but not uniformjs.com implementation. We have saw too that it could be a problem with name instances when they have same name ($). Some help please. Thank you.
