Perhaps I'm not understanding how this works.
I have MC17 up and I have a video paused. From a command line I run:
C:\Program Files (x86)\J River\Media Center 17\"Media Center 17.exe" /MCC 10000, 0
which should issue a MCC_PLAY_PAUSE
Nothing happens, other than the MC window is brought to the foreground. What am I doing wrong?
