you should definitely use the component jacks. The difference in picture quality is noticeable. But, as far as paying beaucoup $$ for special component video cables, it isn't necessary. The only thing that makes those different is the name and thicker wire. Just go buy three decent-quality RCA video cables and plug 'em in to the component jacks. I highly doubt you'd see a difference between that and and a $50 component cable.
