Hi,
On an xbox one since the (plex) update, ALL of my files (x264 / x265) stutter for about the first 10-15 seconds at the start of play, then playback becomes normal. I never had this before the update, same files.
Just a complete guess but it feels like its starting playback before a playback buffer has filled ?
I’m using a wired gigalan, which supplies many android devices without issue (those other plex dont have the stutter)
not a killer bug, but damn annoying.
