Hey everybody.

I'm new to this forum, but i hope some of you might be able to help me. When I try to play some my .m4v-files on the XBMC, the picture doesn't show on fullscreen mode. But when I go back to the menu and the video is just running in the background, it's running perfectly. I've got the same problem when i play on of my video add-ons. I've got absolutely no idea why this is.
I desperately need some help

What happens if you press enter/return a few times?
Does it become full screen?
If so, once it is full screen, go into the video player OSD (press "m" and go to video) and set to use this on all video.
