I've got PMS installed on a linux server, directly hooked up to my network by a cable (not wifi).
When I'm playing videos to my mobile devices, everything works smooth.
Chromecast (wifi): also smooth.
Other computers (cable): same.
Only when I want to watch on my TV (which is a Philips smart TV running Android) with the native Plex app, the first 45 seconds are lagging.
My TV is directly connected by a cable, so there is a direct gigabit connection between TV and PMS.
It lags on every kind of video, even the lowest quality files are lagging.
Does someone has an idea what I can do to fix this (or debug tips)?
