Setup:
- Movies are stored on a NAS (Synology DS412+)
- Using Plex on Xbox One to play movie
- Xbox One is attached to the NAS using a cable (1Gbps)
When not selectng subtitles, movies play smoothly
When selecting subtitles, it needs >15 seconds to play 2 seconds, after which it needs another 15+ seconds to play another 1 to 2 seconds. Basically, I cannot watch any movies when subtitles are selected.
I've tried watching a movie with subtitles a while (~2 months) ago: same issue. I've basically never been able to watch movies with subtitles using the above setup.
As all (NAS, Xbox and Plex) have received updates, I tried again today, but problem remains.
I couldn't find people with simular issues on this forum, but cannot think of a 'user error' that can cause this.
Anyone any suggestions what might cause above issue? Anyone else has experienced this in the past?
