Apple TV Seed Itunes library but won't play anything

I Have a couple lf apple tvs both the newest generation. My macbook is MacBook Pro with retina display and running Mavericks. Today, both apple tvs simultaneously quit playing anything from our itunes library. I can view my entire library on the Apple TV but trying to play one jusy displays spinner forever. If I start it on iTunes and AirPlay it to the apple tv it works, so I know it is not a network issue.

Suggestions?
