UE65MU6179UXZG - hide OSD shown in Videoplayer (via USB) ?

[Labamba]

Hi there,

losing my nerves when playing videoclips from USB:
Everytime the video repeats itself or the next one starts there's the playback-menu shown für several seconds.

Samsung support and user manual deny the option to hide that OSD menu.

Any hacks or shortcuts for me?
Thanks in advance!
