Hello, I am new to Apple Computers and just bought a 15" mbp and apple tv. I now have my itune library on my mbp using my itouch and I have a lot of movies and tv shows. It is taking forever to sync my itunes library over the air. My router is upstairs so I cannot use a ethernet connection from that. I was wondering if their was a cable that I could use to sync my itunes library with my apple tv something to connect between the two. And is their a setting to do this. I tried a ethernet cable but the apple tv thought I was trying to make a internet connection. Please help out a noobie Thank you.
