Strange, the first strace log tells me that the cdrom was mounted with the udf filesystem.
You confirm that after having done: strace mount /media/cdrom0 the UDF-DVD-R was mounted with the iso9660 filesystem ? Can you do a "cat /etc/mtab" after the mount ? -- Mounting UDF should be preferred over ISO9660 https://bugs.launchpad.net/bugs/112584 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
