To add Blue Ray Structure option in PD....

1. Run “regedit” or “regedt32” from Start
2. Go to register current user location: HKCU\Software\CyberLink\PowerDirector\X.0\AuthorPage
(Where “X” is your version 8.0, 9.0 etc.)
3. Right-click on the AuthorPage folder and create a New DWORD value. That will add a new value over in the right-hand pane.
4. In the right-hand pane scroll down to the bottom of the list and rename "New Value" to BurnBDMVFolder.
5. CHANGE THE BurnBDVMFolder VALUE TO 1

Cheers,
Nicolas
