In those days I had the need to copy a DVD with a home movie (recorded by the camera) and burned to a DVD-R with a Panasonic DVD Recorder. Since I had some difficulties, I decided to write this little walkthrough. The whole operation performed by the Ubuntu 10.04 and I can not say if indeed with Windows / Mac or other version of GNU / Linux I encountered the same problems. put the DVD in a regular DVD player table, the movie plays correctly. Even putting it in your computer's DVD player, plays correctly: the movie is played from a standard DVD player such as vlc.
The problem arises when you try to access the mounted directory. For example, if the DVD is mounted by Ubuntu in the directory / media / DVD_RECORDER a cd / media / DVD_RECORDER generates an access denied error.
The problem remains even if you try to force the right to read eg by running Nautilus as root. In this case you can browse the folders inside the folder mounted but you can not copy files from folders to another location on disk.
not personally know the person who made the repayment of the movie on DVD, I do not know for sure whether, in the process of burning, have been set any security details or if the DVD Recorder itself imposed some kind of default protection. The fact is that the DVD will play correctly, but when you try to access in reading is blocked.
What intrigued me is the fact that you are unable to access the list of folders and files and more that we can play the movie on the DVD, but we can not in any way be able to copy the files.
The solution is to use the mount command with the particular option nojoliet .
sudo mount-t iso9660-o ro, nojoliet / dev/sr0 / mnt / dvdrom /
where / dev/sr0 is the DVD device and / mnt / dvdrom directory is Mount .
nojoliet in the description of the man mount is as follows:
Disable the use of Microsoft Joliet extensions, even if available.Well, Ubuntu and Microsoft do not go quite agree ...
