My Apple TV3 will not stream movies and it takes a very long time for music to stream from my MacBook. I readjusted the resolution settings and it was the same thing. It gives me an "error occurred loading this content; try again later" message after spending several minutes of buffering after I try to play movies.
I have high speed 15 mbps Mediacom internet, which has never had any issues. I called Mediacom and they said my connectivity was excellent. I have reset my router/modem/AppleTV to no avail. My homesharing is on and I have followed all other recommendations I could find on Apple forums concerning this same issue.
I am going to return this product for a Roku if I am not offerred a solution on the matter.
Apple, I hope you realize this is not an isolated incident.
