Since switching my ATV3 from wifi to wired a few weeks ago, I haven't had to restart iTunes once. Used to be a daily thing.
are people still experiencing this problem?
I was getting this, and switched from wired to Wifi, and it seemed to fix it. Just put in new Cat5e cable to ATV and would like to hook it up, but obviously not if this is still ongoing!
I think the issue is that the Apple TV is not "waking" the machine hosting the videos.
I was about to give up on home sharing, bought an AirPort Extreme as a last resort and swapped out my old router, now works like a charm.
Go on your Apple TV and set the ip and all network settings to manual. I did this an it fixes the problem . What happens is hole your devise is connected to Apple TV , if the settings are set to automatic, the Apple TV's up changes and yo loose on connection to it so if you set it to manual, you stay connected. I just got an Apple TV a week ago and I did this and now whenever I am connected to wifi, even if my Apple TV is sleeping. I can use home sharing to control it with the remote
