I recently updated my ATV 3 to the latest firmware. Ever since streaming movies from my iTunes on my laptop has been slow. Movies always stopping and buffering. Even with home sharing turned on sometimes it won't connect to my laptop and read my library. I have to constantly restart the ATV. I've checked my internet and the speed is fine. I've reinstalled iTunes on my laptop and reset the ATV to factory settings. Same problem. Never had any issues before I updated. Anyone else having problems?
