I am currently digitized a bunch of DVDs. Some are encrypted, and some are not. My method for digitizing a DVD depends on whether or not it is encrypted, so I am looking for a command-line method to determine if a DVD is encrypted or not.

\**Note:* I know that DVDs are often encrypted with the [Content Scramble System (CSS)](, and that you need to install a package such as [libdvdcss]( to read encrypted DVDs.
