Problem description:
When ever i Play an MKV its just.. randomly stops and im back in the XBMX gui.
If i restart the movie/serie it starts just where it droped out. And works
for a while or a second and drops out again. Same story with all my mkv and
they all work on my boxee box and computers.

How to reproduce:
