that's called component video. It can give you the best picture quality with analog cables (I think it's analog). You will need a TV with component video in (or sometimes referred to as ColorStream HD). The black one is the s-video cable I believe. Many TVs have S-video. Unless your TV is very old, it may or may not have an S-Video Input. It won't give you thebest quality but it'll be nice for movies. Either way I would recommend Component (even better, go with DVI if your TV has the port at the back for it).
