Currently, i'm only utilizing one device over Home Sharing.
From what I can recall, deleting some songs from my library helped alleviate the problem the first time.
This time I unplugged my AppleTV, limited the Home Share amount to only a few playlists, and voila! it ends up playing just fine.....for now!!
Maybe you can help - I'm getting shrugged shoulders and no commitment from the "Apple Gurus" at my local store:
I have a client who has a large house with 8 Apple TV 3s sharing from a Mac Mini, and he wishes to add to his setup.
He would like to add an Apple TV to all of his TVs, bringing the total Apple TVs to about 40!
Is this possible? or will the system not work with more than 10 Apple TVs on 1 Apple ID?
