Ripping DVDs

• ddrescue
• pv
• vobcopy

The term “ripping DVDs” is associated with ripping a DVD and encoding it to an alternative format. When I refer to ripping a DVD in this wiki, I use it in the context of only ripping the content from the original format of physical media. Not to worry though, there's lots of other stuff on here about reencoding DVDs on here in the software sections. :)

The reason I focus mainly on copying the content is because I like to archive my discs. They are going to run generally from 4 to 8 GB in size. Storage is cheap, but that's not the main reason I rip mine – it's so that I can access *all* of the content whenever I want. I don't have to go back and grab the disc.

The file extension ISO has also become associated with a DVD rip, or really any image of any DVD or CD. It's a misnomer, since for video DVDs, the filesystem format is UDF. I'm not a fussbudget when it comes to using correct terminology, though, so I'm not going to beat it into everyone's head that they're doing things wrong. :) I use the .iso extension exclusively. The only reason for pointing out that the file format is UDF is that it is important when trying to mount an ISO.

When I refer to “an ISO” in my notes, I am always using that term to describe a DVD that has been cloned from the physical media to the hard drive as a single file.

Using the term “extracting an image” is more close to what I'm doing when I rip, so I may sometimes use that phrase, too. :)

The best way to rip to an ISO is to copy the entire contents of the disc. For that, I use dd with pv or ddrescue.

There are other ways to copy the DVD, such as vobcopy, but these programs are designed to rip parts of the DVD or to mirror the filesystem another way.
