It finds all the titles fine, but when playing back, the sound is often out of sync by 2-5 seconds, and subtitles are off by 10-15 seconds. You can adjust the subtitle offset through trial and error and maybe get them close, but there's no way to adjust audio sync.

Disabled "Prefer fMP4-HLS Media Container" based on this recommendation: https://github.com/jellyfin/jellyfin/issues/11723

Rebooted and updated all parts. Still didn't fix the issue.

Any other suggestions? It happens across multiple titles.

Force transcoding and burn in subtitles

EDIT: explain the downvote? This is the correct solution lol it's not a problem with your client

Toggled burning on and found could also adjust subtitle size and position. It says it might affect performance, but that machine doesn't have too many things running on it.

I also remembered it would get worse as you scrubbed or paused, then played. Hopefully, the burning will help avoid that. Thanks!

The performance hit during play and scrubbing is due to need to transcode the video as it burns the subtitles in. If you have hardware acceleration for transcoding configured properly, it shouldn't be a big impact on modern hardware
