There are several ways to backup DVD videos; see DVD Ripping. Many methods are slow, and require several steps to accomplish. Template:Package AUR provides a simpler method (with some help from Template:Package Official). The Template:Codeline program is elegant because it does not demux/remux/transcode/reformat the movie. This means the backup process is done in one step.

Installation

Template:Package AUR is available from the AUR.

Template:Package Official is available in Template:Codeline, but is only required if backing up specific titles or title sets.

# pacman -S dvdauthor

Template:Package Official is available in Template:Codeline and is required to read encrypted DVDs:

# pacman -S libdvdcss

Examining the DVD

First, determine which title to backup. The following command retrieves information about the DVD:

$ dvdbackup -i /dev/dvd -I

After some less useful information, Template:Codeline will display something similar to the following: Template:Command

This indicates that the main feature is in title set 1. Next a list of title sets is displayed: Template:Command

The main feature in this example is title 1. Sometimes a title set will include more than one title, sometimes not. Title sets can also include menus, which will no longer work if not backing up the entire DVD.

Ripping the DVD

Tip: Template:Codeline reads the name of the DVD and creates a working directory for it. If Template:Codeline decides the name of the DVD is too generic (like MOVIE, for instance), the user must specify a name, as it will refuse to run otherwise. Just use Template:Codeline to specify.
Note: If you receive an error such as "ERR: no video format specified for VMGM" you must set the video format variable. An easy way to do this is to add Template:Codeline (for NTSC regions) to your Template:Filename.

A single title

The Template:Codeline option allows you to extract a specific title:

$ dvdbackup -i /dev/dvd -o ~ -t 1

You will now see a number of VOB files on the hard drive (in Template:Filename). These files can be played in MPlayer or VLC, but are insufficient to create a DVD copy! This is where Template:Codeline is useful.

A title set must now be created (e.g. Template:Filename and Template:Filename). Be aware that the following command will make a copy of the entire movie. The original can be deleted right afterwards.

$ mkdir ~/dvd
$ cd ~/MOVIE_NAME/VIDEO_TS
$ dvdauthor -t -o ~/dvd *.VOB

Template:Codeline will create a copy of the movie. If it outputs anything like "SCR moves backwards, remultiplex input" there might be trouble. Before deleting any files, check the file sizes of the original VOB files compared to the copied ones. If all roughly the same size, you may be alright. You can use MPlayer to test the affected VOB files to see if anything is missing.

Now, table of contents files must be created (e.g. Template:Filename and Template:Filename). This is much less time-consuming, and does not waste hard drive space:

$ cd ~/dvd/VIDEO_TS
$ dvdauthor -o ~/dvd -T

The main feature

The Template:Codeline option automatically detects the main feature (though not always correctly!) and copies the entire title set:

$ dvdbackup -i /dev/dvd -o ~ -F

Now, table of contents files must be created (e.g. Template:Filename and Template:Filename):

$ cd ~/MOVIE_NAME/VIDEO_TS
$ dvdauthor -o ~/MOVIE_NAME -T

The whole DVD

The Template:Codeline option will backup the entire DVD structure, including menus, special features, etc. This requires approximately 7 GB of disk space for most DVDs:

$ dvdbackup -i /dev/dvd -o ~ -M

Writing to disc

See DVD Writing.

Creating an ISO

The advantage of creating the ISO file is that you can test that everything works fine with MPlayer before continuing. The disadvantage is that the ISO consumes hard drive space.

$ mkisofs -dvd-video -udf -o ~/dvd.iso ~/dvd # if a single title was extracted

or

$ mkisofs -dvd-video -udf -o ~/dvd.iso ~/MOVIE_NAME

To test the image with MPlayer, simply:

$ mplayer dvd:// -dvd-device ~/dvd.iso

If everything seems fine, burn the image:

$ growisofs -Z /dev/dvd=~/dvd.iso

Burning straight to DVD

If confident in our skills, creating and testing an image is a waste of time and hard drive space! Basically, one can merge the mkisofs with the growisofs command listed above:

$ growisofs -dvd-video -udf -Z /dev/dvd ~/dvd # if a single title was extracted

or

$ growisofs -dvd-video -udf -Z /dev/dvd ~/MOVIE_NAME
