how to stop a music through dbus
 

Hi,
I am developing an app that plays some bird songs through the default mediaplayer of the N800. I know how to start playing a bunch of files with dbus:

dbus-send .... com.nokia.mediaplayer.mime_open ...

How can I use dbus-send to pause/stop playing the music? Yes, actually my problem is that I don't know how to use dbus...

Thanks!!
