SVN commit 530869 by vriezen:

Adding a isPlaying() dcop call for the backends, that can be used to 
determine actual playing state (false on not playing or paused). Since 
this is a synchronious call, I rather not use it for the KMediaPlayer 
dcop interface (and this would also have a different meaning when 
backend is MPlayer then)

CCBUG: 125761

It ´s better than nothing, so w/
  dcop kxineplayer-pid Backend isPlaying
or
  dcop kgstplayer-pid Backend isPlaying
you could solve it for your case, probably better to do the  ´pause() ´ 
call on KMediaPlayer interface of kmplayer.
