I have a DVD which I can open in Windows, but in my Ubuntu 12.04 installation I cannot any more. I receive this error:
Unable to mount UDF Volume Error mounting: 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
What should I do to open it? Do I need to install anything?
