Problems accessing movies on MacBook Pro via Apple TV I've got a MacBook Pro and Apple TV, and I can search and select the movies found within the MacBook Pro's iTunes from the Apple TV's > Computers menu.

The problem is that when I try to play the movie from the Apple TV, it often freezes with the "loading" spinner, without playing the movie. If I hit the Menu button on the Apple TV remote, the Apple TV responds instantly, so it's not that the Apple TV has frozen. 

If I instead start the movie from iTunes on the MacBook Pro, then display it on the Apple TV via AirPlay from the MacBook Pro's Display settings, the movie starts instantly and is shown on the Apple TV.

Why can I "push" the movie from the MacBook Pro to the Apple TV via AirPlay, but not "pull" the movie from the Apple TV's interface?
I had the exact same problem as this before. Any number restarts and reboots in any order did not solve the problem.

At the same time I had a DNS issue with the default router setup from my ISP. When I changed my routers DNS to use the Google DNS it also solved my iTunes sharing problems. 

I don't know if this is actually what caused it or if it was just a big coincidence but it's been working fine ever since.
