I am debating on buying either the Composite or Component AV cable for my iPhone to play movies on friends TVs. I want to buy the one that is gonna work on the bulk of TVs out there. The trend seems like most even new TVs will have RCA inputs but I know lots of old TVs wont have component. So based on the idea of which one I am going to be able to use on most TVs, which one should I go with? As much as quality is nice with the component, if you can't plug the cable into the TV, quality is a waste since you cant watch anything. Thoughts? Thanks!
