DVDFab Passkey for DVD is a Windows-based driver that can unprotect encrypted DVDs, letting you access and watch any DVD movie freely without any limitation.
It can remove DVD copy protections and region codes in seconds, including RC, RCE, APS, UOPs, ARccOS, RipGuard, etc. Still, the software has been constantly updated so it can deal with new DVD protections.
Besides DVD decryption, it can also work with a wide range of other software to edit, copy, burn, and clone the decrypted DVD content as you need.
It comes with flexible settings, allowing you to remove PGCs for the output movies, change the DVD playback order, specify a language, etc.
