Frequent intermittent pauses when playing video on new QNAP Plex server

From you server log, I can see that every attempt to play a video is causing subtitle decision=burn.

Subs must be transcoded on the CPU. That’s likely bogging down your system. You are not the first person this is happening to on QNAP 4.4.1 + PMS-1.18.0 lately. See also PMS on QNAP TVS951x - Buffering. all the time

There are some other errors in there too. Let’s check on those while you’re here.

Can I ask you to stop the PMS application on the QNAP, then start it again, and give it 6-10min to initialize. Then hop on the web app and Settings - Troubleshooting - Download Logs for me please. Zip up what it gives you and attach it with your next reply. That will show a clean boot and any foundational problems.
