1. A method of preventing unauthorized recording of electronic media comprising:

  • activating a compliance mechanism in response to a client system receiving media content, said compliance mechanism coupled to said client system, said client system having an existing media content presentation application operable thereon and coupled to said compliance mechanism prior to said client system receiving media content;

    controlling a data path of a kernel-mode media device driver of said client system with said compliance mechanism by diverting a commonly used data pathway of said media content presentation application to a controlled data pathway monitored by said compliance mechanism for all received media content regardless of a usage restriction thereon, said compliance mechanism utilized to stop or disrupt the presenting of said media content at said controlled data pathway when said presenting of said media content is outside of a usage restriction applicable to said media content; and

    directing said media content from said kernel-mode media device driver to a media device driver coupled with said compliance mechanism, via said data path, for selectively restricting output of said media content.
