Without sample files or logs, there’s nothing I can do. All 4k files I’ve tested with work fine.
Are you playing with subtitles? If you’re playing PGS/Vobsub subtitles, it’ll transcode because Samsung doesn’t support Image-based subs. If it’s srt subtitles, there’s a bug where after a while of playing a video, it switches over to transcoding (this is fixed for our next Samsung released). If there’s no subtitles involved, we’ll need sample clips or logs to figure out what’s going on.
