- I am currently ripping a bunch of DVDs. Some are encrypted, and some are not. My method for ripping 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.
My current way to detect whether a DVD is encrypted or not is that if it is encrypted, then running `dd if=/dev/sr0 of=file.iso` results in "Input/output error".- \**Note:* I know that DVDs are often encrypted with the [Content Scramble System (CSS)](https://en.wikipedia.org/wiki/Content_Scramble_System), and that you need to install a package such as [libdvdcss](https://www.videolan.org/developers/libdvdcss.html) to read encrypted DVDs.

how to determine if a DVD is encrypted from the command-line
- how to determine from the command line whether a DVD is encrypted
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)](https://en.wikipedia.org/wiki/Content_Scramble_System), and that you need to install a package such as [libdvdcss](https://www.videolan.org/developers/libdvdcss.html) to read encrypted DVDs.

how to determine if a DVD is encrypted from the command-line
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)](https://en.wikipedia.org/wiki/Content_Scramble_System), and that you need to install a package such as [libdvdcss](https://www.videolan.org/developers/libdvdcss.html) to read encrypted DVDs.
