This code does the following: - if kaffeine (KDE video player) is running, a play/pause signal is sent to it - if tvtime (TV application) is running (but not kaffeine), the picture is paused and the sound is muted in tvtime - if none of the above, XMMS (X Multimedia System, like Winamp) shall play/pause
