Ok when I click on "computers" on the Apple TV home screen I see both my desktop and laptop libraries in there. However when I click on them, it says libraries are empty. I checked both comps to make sure home sharing was on and it was. I also unplugged and replugged it in to see if that worked. Also tried a different tv........same thing. I checked to see if maybe I was needing a software update but that was up to date along with my current router settings. I searched this board and couldn't find anything. The only thing I can think of is I switched to the new Airport Extreme recently, but I believe I have listened to music over my ATV since then, but can't be sure.......however I don't see how that would be causing a problem, especially when my ATV sees the libraries just says they are empty. Thanks!
