This problem is simple: I burn a new DVD session using dvd+rw-tools
7.1-6 (kernel 2.6.23), and output seems to show it is successful. Then
I offload it from the drive, insert again, try to mount it, and failed.
A few trial shows only if I mount by specifying iso9660 as file-system
explicitly, can the mount be successful, and correctly mounted to the
last session. The very same CD, if inserted to Windows XP, mounts fine
but mounted one of the session before last. Expected behavior is: that without any parameter like filesystem and session ID, the DVD should mount to last session on it on both Linux and Windows XP. What cause the behavior different from expectation? Below I have the following references:
