Do you need composite cable with universal dock or will dock allow you to watch iPhone videos pics etc through tv?

I have an iPhone and want to watch videos through my tv, can this be done with the universal dock or composite cable or do I need both?
I also have surround sound with iPod/iPhone dock which allows me to listen to my tunes but doesn't allow visuals, does anyone know how this can be achieved?
Many thanks
