ATV3 pausing airplay every 10 minutes

My thoughts

It could be buffering. Perhaps there was a lot of network activity on your wireless connection and the AppleTV was buffering the data stream.

I had this with the original ATV. Drove me up the wall and never found a solution other than to sync to the HDD on the ATV before attempting to view anything. I still do it to this day (perhaps more out of habit as the problem may have solved itself).
