Hi I would like to use my new macbook 13(aluminum) as a display to play the sony PSP. The PSP can be played on a tv via component or rca. How would I get video in to my macbook? and how would mac os interpret that? would a DVI adaptor to rca work? http://store.apple.com/us/product/M9267G/A or is that video out on my macbook? thanks!
