i think that you have not http://madshi.net/madVR.zip properly installed on your system, anyway you should provide a debug log, all information on how to do that are at first page under "How to help:"

Ok I went through the manual setup as posted in the quite and still just get blank screen each time I play a media file and I can't do nothing else unless I reboot the system.

That is with dsplayer enabled.

here is the debug log.

Many Thanks

In Kodi, system settings, have you selected use fullscreen window?

Yes, it was in the guide. I will try with it off and test again.
