The optical drive firmware and region management software restrictions that
prevent "Region Free" playback are part of the process used to decrypt the
DVD. VLC uses a library (libdvdcss) that accesses the DVD like a block
device bypassing the decryption process altogether. No invasive and risky
firmware update or third-party region-changing utility is needed.

In addition, bypassing the decryption process also eliminates the need for
the user to make region changes that require administrator rights. In this
way VLC is ideal for an open lab setting. Effective playback of a foreign
DVD with VLC, however, is possible only if the system and the application
are configured correctly.
