Why is PS4 media player 10-20 times faster than Plex media player on the PS4?


Recently I have switched from the Plex media player to the PS4 media player on the PS4. The main reason is that the PS4 media player is 10-20 times faster to start playing/fast forward/reverse for the same content. In deed, if I press 'skip 30 seconds' or 'go back 10 seconds' using the Plex media player, I sometimes have to wait 10 seconds before it starts playing again. But on the PS4 media player, playing the exact same content, it starts playing right away (less than one second).
I wish there was a setting to solve this.


By the way, I tried posting my question in another thread but only this one and ‘news’ was available for selection…
