Hi
Thanks alot, will try that now... I was left under the impression that 
the way I was doing it was the standard way from the examples in th "How 
to..."
I saw this threaded stuff in the source code but could not really figure 
out what it would change...

Good luck in Munich, I'm from Germany myself :)

regards,
Ole

You have several client<->player modes. Check
http://player.robotux.info/group__player__interface__player.html#ga14 for
details.
