    Help please. [dvdbackup, dvdrip, handbrake] not working.


    Hello guys,

    I was trying to make a backup of my DVDs and I can't seem to make "dvdbackup -M" work.

    Code:
    jun@jun@ldme ~ $ dvdbackup -M
    libdvdread: Using libdvdcss version 1.2.11 for DVD access
    libdvdread: Can't stat /dev/dvd
    No such file or directory
    libdvdread: Could not open /dev/dvd
    Cannot open specified device /dev/dvd - check your DVD device
    jun@jun@ldme ~ $
    I tried using handbrake but am getting errors. Also with dvdrip. Please note that I also attached a png file of a screenshot which shows that the dvd has 191 files and 63 G of data. Is there a way I can work around this problem please. Thanks!


    regards,

    nujinini

    Hi nujinini,
    I don't use dvdbackup, but it sounds like its expecting a DVD to be mapped to /dev/dvd and its not there. Can you ensure that is true with an "ls -l /dev/dvd" in a shell window? To find out were it was mapped to, try re-inserting the DVD then wait for the LED to stop flashing, then look at the end of the text "dmesg" produces. Once you identify were your DVD is, it looks like you can use the "-i" command switch to specify the correct input device according to this manpage:
    Ubuntu Manpage: dvdbackup - Tool to backup DVDs

    i personally use dd to backup stuff insert the dvd then run "dmesg | tail" it will tell you the linked file to the device which is mostly "/dev/dvdrom"
    or something like that then use "dd if=/dev/dvdrom of=backup.iso bs=4096" to start the backup you can say it will "clone" your dvds to a file

    What program produced the screenshot that you show? Does it give a clue as to what device the DVD reader is shown as?
    It is hard to believe that a DVD which natively holds 4.7GB of data could be encoded to have 63GB of movies.

    Hello BrianMicek,

    Thank you. I don't know if this output is saying something about this output but just the same, here goes ...
    By the way, the dvd is already read by the system and ready to play too. FWIW.

    Code:
    jun@jun@ldme / $ ls -l /dev/dvd
    ls: cannot access /dev/dvd: No such file or directory
    jun@jun@ldme / $ cd media/
    jun@jun@ldme /media $ ls
    cdrom                 Family Entertainment_  Personal Stuff    Storage
    cdrom0                floppy                 Personal Stuff_   XP-Windows
    Family Entertainment  floppy0                PR4-0H-LW1.1_DES
    jun@jun@ldme /media $ ls -l PR4-0H-LW1.1_DES/
    total 12
    dr-x------ 2 jun jun   40 Jul 12  2011 AUDIO_TS
    dr-x------ 2 jun jun 9868 Jul 12  2011 VIDEO_TS

    Code:
    $ cat /etc/fstab
    # /etc/fstab: static file system information.
    #
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    proc            /proc           proc    defaults        0       0
    # / was on /dev/sda1 during installation
    UUID=51c3d28d-d8d5-4b78-ae3d-1f472b8186e1 /               ext4    errors=remount-ro 0       1
    # swap was on /dev/sda5 during installation
    UUID=cda87444-c374-4107-aed7-03e455e26fcf none            swap    sw              0       0
    /dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
    My DVDRW shows as /dev/scd0 on my box nujinini in /etc/fstab.

    You might want to check yours to see what shows for dvdrw on your box. Then adjust preferences in what ever program you are using to match /etc/fstab entry.
