Several Attempts to play MTP Daily S2020E208 2020-10-15-1659 on the Shield Emby Client at around 13.03 failed after about 1 second with a spinner and a "too many errors" message.
Playing the same program through the WebUI worked normally.
After waiting for running scheduled tasks to finish, I stopped the server from the WebUI dashboard and then restarted the Shield.
The program then played normally on both devices.
I have additional ffmpeg-directstream logs from playback attempts, all of which show the same "[q] command received. Exiting." message as the attached example.
