Easiest way to clone/backup DVD-collection

I have a bunch of dvd-movies and tv-shows on dvd. I would like to make copies of these, preferably to blank dvd:s. Doing this I want to keep the data as close to original as possible, meaning I want to keep the dvd menus intact. How would I do this? What kind of software would I need?

Thank you.

  1. Edit: added considerable detail after switching devices.

    Plain ISO copy typically does not work due to copy protection on commercial videos.

    Copy protection tricks:
    * CSS – the data is encrypted on the disk using a primitive algorithm. The data needed by the drive/player to decrypt will be lost on a raw iso copy. blu-ray has a much stronger encryption algorithm.
    * intentionally bad sectors (Arcccos and ripguard) – cause raw disk or file copying software to hang or be very slow. DVD player following menus normally never accesses those sectors.
    * corrupted data in menus.
    * files with bogus sizes (i.e. much bigger than will actually fit on disk or 0 bytes)
    * barcode burned on disk in burst cutting area with a different kind of laser but readable by player as well as with the naked eye and may or may not be checked by java code in menus. Also, even without the barcode there is a media ID on the original disk that is not copied.
    * analog protection – specific scenes are corrupted during playback to prevent analog copying. Companies pay based on the number of frames they corrupt, so video may look ok until you get to a good scene. Some dvd copying software will remove the bits that instruct the DVD player to do that.
    * cinavia – encodes a signal in the audio, regardless of how the audio is copied, that most blu-ray players will detect and disable playback but it won’t significantly affect your ability to play it on computer/streaming (unless you use a DVD/blu-ray player as a streaming device?) other than the reduced audio quality inherent in cinevia encoding. Blu-ray players manufactured after 2009 and DVD players manufactured after 2012 required to implement. If you stopped buying DVDs when blu-ray/streaming came along, then your DVDs probably don’t have it.
    * double layer disk. Not copy protection but people who copy to DVD often use single layer disks so you need to shrink video files to fit on single layer disks with handbrake, dvdshrink, etc.
    * region code enhancement – inserts an infinite loop of a map into your video region coded in such a way that region free players will accidentally play it while a region 1 player will skip it.
    * Many copies of the VOB files tha contain the video in many possible combinations of order, only one of which is correct. A form of structure protection.
    * [others](https://en.wikipedia.org/wiki/List_of_Compact_Disc_and_DVD_copy_protection_schemes)

    A DVD video disk consists of a combination ISO9660 and UDF filesystem (two separate filesystems pointing to (mostly) the same file contents, containing some .VOB files (video/audio data) and .IFO files (menu data) and .BUP (backups of .IFO) in the /VIDEO_TS/ subdirectory. An /AUDIO_TS/ subdirectory contains audio files, if any, intended to be played without video (as an alternative to audio CDs) and some players won’t work without it even though it is usually empty. Additional data may be stored on the disk as extra features for use with a computer. There is a volume label on the filesystems. All of the preceeding is contained in an ISO image of the disk. Media ID, CSS keys, and burst cutting area are separate and do not copy. A DVD player typically reads the UDF filesystem and a computer typically reads the older ISO9660 filesystem although newer systems may be able to mount the UDF filesystem instead. The DVD player also reads the data in the IFO files and those tell it where to find the video data. Video in the VOB files may be out of order or contain extraneous video or video from alternate cuts of movie and a track may be split between multiple VOB files. Each VOB contains multiple Cells and the IFO files tell it what cells to play in what order for each video track. The theatrical release and the directors cut, for example, may contain some of the same cells while others are different. Since the main tracks are likely longer than the maximum file size on ISO9660 or 32bit operating system, the video data is broken into multiple VOB files.
    Programs:

    * IFO/libdvdread based
    * vobcopy in mirror mode (-m). command line
    * dvdbackup in mirror mode. command line.
    * windows freeware (works in Wine on linux)
    * Ripit4me (wine or windows). Runs dvddecryptor, FixVTS, and dvdshrink with one click, also patches some issues that they don’t.
    * dvdshrink – see ripit4me
    * FixVTS- see ripit4me
    * dvddecryptor – see ripit4me
    * Sector by sector
    * ddrescue -n -b2048 /dev/dvd copy.iso copy.map – copies disks and tries to read around bad sectors intelligently to get the good data first. Short options shown same as ddrescue –no-scrape –sector-size=2048 … -v/–verbose switch can be used and -r 5/–retry-passes=5 can be used instead of -n/–no-scrape if you want to try harder to read bad sectors in case you have some non-intentional disk damage but this may take longer.
    * dd conv=noerror,sync bs=2048 – use ddrescue instead. dd behavior in response to bad sectors is frequently incorrect though using noerror,sync and matching the blocksize on disk exactly will probably work.
    * Commercial
    * makemkv $- backs up menus on blu-ray but not DVD. good at getting video off DVDs. Linux native version available.
    * DVDfab $$$ (windows or wine). Only one that can remove cinavia
    * free open source GUI
    * handbrake – always shrinks/recompresses video. will use libdvdcss if installed.
    *Related
    * Libdvdread/libdvdcss used, if installed, by some of the programs to unlock CSS
    * Dvdauthor or mkisogs –dvd-video can be used to make DVD video from extracted files
    * cvlc –run-time 6 –start-time 16 /dev/sr0 vlc://quit (see below)
    * loopback mount on linux and other unix-like operating systems has let you mount an iso file for decades. use “mount -o loop …” or losetup. Other operating systems have more recently [added the ability](https://en.wikipedia.org/wiki/Loop_device). There is also [powershell trick](https://superuser.com/questions/1133081/what-is-windows-way-to-do-mount-o-loop-rw-offset-x)
    * fuse filesystem (linux) – some filesystem drivers such as fuseiso will let you (or your media streamer daemon) traverse inside ISO files transparently. Some of those might even work on FUSE clones on other operating systems.
    * cp, xcopy, robocopy – copy files, optionally recursively. Probably not going to work very well as it will be broken by almost any form of copy protection.
    * CinDe – cinavia detection. [Questionable](https://forum.videohelp.com/threads/362806-A-new-version-of-DVDRanger-CinEx-HD-that-is-a-scam)
    * IsoToMKV – powershell script. uses makemkv

    * Players:
    * VLC runs on most desktop OSes and there is an app version for mobile/streaming box. Even the android/firetv version is repordedly able to play ISO files or a mounted iso.

    Kodi, SPMC, Plex, or VLC can play MKV on a fire stick.

    For some programs, like ddrescue and dd, you may need to play a short portion of video with vlc or cvlc before copying to unlock CSS.

    Using ddrecue, dvdbackup, and mkisofs in order: [https://cmdln.org/2010/01/22/backing-up-disney-dvds/](https://cmdln.org/2010/01/22/backing-up-disney-dvds/)

  2. You need disc imaging/cloning software to make a .ISO image file from a DVD. Then you can burn it to make a copy with disc burning software.

  3. I haven’t done it in a long time, but back then I was using Dvd shrink to make an .iso of the disc, and then burn it back to a blank dvd. Just be careful, dvd shrink usually compress the files to fit a single layer (4.7GB) dvd, you can set it to uncompressed to fit a dual layer one, which is used by most movies.
