Ok so i was able to move my iTunes library to an external drive attached to my airport extreme, and have all the content play in iTunes. When i went down to use my apple tv 2 tonight, it says there are no movies, and no music in my library. I was able to go into iTunes and click the airplay icon and it played on the ATV 2 but it won't work the other way around. So I'm sure people have done the same thing i have done so how can i fix this?
