jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv on my NEXBOX ultra cheap box. Note: the media must be local as the ethernet will not keep up.
I can play perfectly only the jellyfish-30-mpbs-hevc.mkv and jellyfish-110-mbps-h264.mkv but not the higher bandwidth files without stuttering.
I play the files from USB HDD (WD 2TB).
What could be the reason?
