The Windows Media Player Plugin module is designed to operate within Windows Media Player™ version 12 (up to 9). It enables a user to cut or edit out a part of media file directly from Windows Media Player™ at high speed without quality degradation and problems with audio/video synchronization.

  2.  If it is disabled click main menu item «Tools->Plug-ins->SolveigMM WMP Trimmer Plugin» to enable it (Figure 2). 

If the main menu of Windows Media Player is switched off, right mouse click at the upper area of Windows Media Player and follow same menu items.
