    Can't Mount DVDRs


    I'm having problems mounting DVDRs into my dvd drive. I can mount CDRs no problem, if they contain both data or music. DVDs with data doesn't want to mount. Here is the error I get while trying to mount it.

    joelcormier@ubuntu:/$ sudo mount /dev/sr0 /mnt
    mount: block device /dev/sr0 is write-protected, mounting read-only
    mount: wrong fs type, bad option, bad superblock on /dev/sr0,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so


    Reading some other threads, I found that most people were asking for sudo lshw -C disk, so I'll post it here.


    joelcormier@ubuntu:~$ sudo lshw -C disk

    Try using the command as shown above
    Code:
    dmesg | tail
    post any errors you find regarding the DVD drive.

    Are these valid DVD's that work in Windows?
    Is this the same command that you mount CDR's with?

    Ok I think I know what the problem is. I tried a few CDs and DVDs, and most work. It's that single one that doesn't work. It does work in Windows.

    I burnt the CD on my laptop which uses Vista. I read on a thread that if you burn on Vista, it might cause problems. It didn't say how to fix it however. The threads that I read were about a year old.

    When I open the "Computer" window and look at the drive, it says "UDF Volume". Other cds say images, or easyshare, or whatever.

    I had this same problem when trying to help another user, just like yourself, trying to figure out the same thing. It might be a Vista problem but I have no idea if this is true or not. I wonder if you can play DVD movies, like say "Pirates of the Carribean". I'm pretty sure that is a UDF disk and not everyone can play UDF disks. If that is the case, then you'd need to recompile your kernel to include UDF support either as a module or built into the kernel itself.

    I tried a regular DVD


    File reading failed:
    VLC could not read the file.
    Playback failure:
    VLC cannot set the DVD's title. It possibly cannot decrypt the entire disk.
    Your input can't be opened:
    VLC is unable to open the MRL 'dvd:///media/SUPER_SIZE_ME/VIDEO_TS/'. Check the log for details.

    VLC cannot set the DVD's title. It possibly cannot decrypt the entire disk.

    Have you installed the DECSS software on your system? WIthout it, you probably won't be able to access a copy-protected video DVD. These are the libdvdcss library files, which VLC and other video players can use if they are available. If not, then they won't play a CSS-encoded DVD.
    Sometimes, real fast is almost as good as real time.

    Ah! I just took note of the fact that the problem is with DVDR discs - recordable discs. Are these pre-recorded discs? If so, I have had similar problems with some DVDR media, that required a firmware update on the drive in order to read the discs.

    The problem is not with all DVDs, just certain ones. I think this one that doesn't work got burned in windows. It contains pictures.

    The other one that doesn't work is an actual DVD (not a DVDR) and it's a movie. I'll try the solotion that you posted for this one. I'm still not sure about the first one though.
