I cannot mount a data DVD using Ubuntu 12.04.

I can read the DVD using a different OS, so the DVD is not the problem.

I can read other CDs using Ubuntu.

The error I get is:

$ sudo mount /dev/dvd /cdrom
mount: no medium found on /dev/sr0

The relevant output from lshw is:

        description: DVD reader
        product: DVD/CDRW UJDA775
        vendor: MATSHITA
        physical id: 0.0.0

        version: CB03
        capabilities: removable audio cd-r cd-rw dvd
        configuration: ansiversion=5 status=nodisc

I have installed ubuntu-restricted-extras and run /usr/share/doc/libdvdread4/install-css.sh.

When you say you can read the DVD on a different OS, do you mean in the same computer/drive? Or on another computer? –  psusi Dec 3 '12 at 16:26
