I have 1TB NAS drive on my wired network. And my apple TV on my wireless network. I have dragged all my movie files from my NAS to my macbook pro itunes whilst holding down the option key - so that the files are not recopied to my macbook pro. That part is all good. But how do i get apple TV to have access to the movies without copying them all over to the apple TV itself? Whenever I sync my apple TV it copies over all the files and fills up in no time. I just want it to reference the files off the nas drive. I know my macbook pro needs to be on for this as apple tv needs itunes - which is cool. How do I do this?
