My DVR server is on MacOS on Apple Silicon and has been working flawlessly for a few months. Suddenly the past few days all the live TV channels will stutter every few seconds, and recordings get very jumbled, suddenly jumping backwards a few seconds from time to time while watching. TV sources include Locast and DirecTV — both stutter.
The stuttering happens while watching on both Apple TV and when watching on the server itself. Server software says up-to-date. Speed test to the server from the internet is >800 mbps.
Any ideas?
