[PROBLEM] long working message

[KoninK]

since a few weeks I've got a rpi3 with xbian, almost everything works except an irritating first world problem.
every time i want to play a file a pop up shows telling me kodi is working, this stays the same for about 2 minutes followed by an error message that playback has failed. when i then immediately play the file again, it starts without problems.

no big deal, but on an evening of watching multiple episodes it becomes annoying as hell.

if anyone encountered this before and has a solutions, please let me know.
