I've been in the wiki but can't seem to get it working.
I have an already open instance of mc and I want it to play a file in fullscreen when mc is not the selected application. I've tried the following:
c:\program files\j river\media center 14\media center 14.exe /fullscreen /play "c:\users\jmccall\videos\cars.m4v"
c:\program files\j river\media center 14\media center 14.exe /fullscreen /playreplace "c:\users\jmccall\videos\cars.m4v"
c:\program files\j river\media center 14\media center 14.exe /fullscreen /command play "c:\users\jmccall\videos\cars.m4v"
In fact if I have an already open instance of mc I can't even play get the file to play with the following:
c:\program files\j river\media center 14\media center 14.exe "c:\users\jmccall\videos\cars.m4v"
But it will play with the above command line if mc is closed.
