You can access the media link exporter by choosing Export from the File menu in QuickTime Player, then choosing Movie to QuickTime Media Link. You can either click Save, which creates an XML file with the default settings, or click the Options button to specify the settings yourself. (Note that Export from QuickTime Player requires QuickTime Pro.)
