I have setup another user called "Kids" and am trying to switch back and forth between that and the Administrator account using MCC. Does the user id parameter start at 0 or 1. Is the Administrator account 0 or 1? I have tried 0, 1 and 3 for the parameter but MC never seems to switch the user. This is the syntax I am using "mc20.exe /MCC 22028,1" Anyone know why this isn't working? Other commands are working such as mc20.exe /MCC 10001 to start playback.
