I think you first have to know if the protection is Hardware
or software based!
If its hardware there´s not much you can do but open the drive and (I´m not sure about this!) installing a microchip that will bypass the protection!
If its software based you can get a crack for your DVD
viewer (Easyer) or removing and re-installing the software
again and again !
Better burn in Hell with some company than freeze in Heaven all alone
