Late 2012 quad core apple mini running server, Apple TV 4 and iOS clients.
Major buffering issues, like every 1-2 minutes with only one transcoding stream. No matter what quality I chose in client side, issue remains. It will even buffer (although less, maybe once every 5 minutes) with optimized versions.
Not network issue, can stream original versions (full bit rate) using DNLA using my NAS.
I did a clean install and it was good for a couple days, now back to the same buffering issues.
Help!
