Remarks

This method sets the access level in the MSVidWebDVD object, which determines what content the user can play back. Higher levels can play lower-level content but lower levels can't play higher-level content. The exact meaning of the eight DVD parental management levels varies depending on the country/region. In the United States and Canada, the levels are mapped to the Motion Picture Association of America (MPAA) rating categories. Parental management is disabled by default. 

  • Note   Player parental levels can only be set in the Stop domain.
