sudo lshw -C disk I get

sudo mount /dev/sr0 /dev/dvd I get:
sudo mount /dev/sr0 /dev/dvd mount: /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.
And when I once hit the Esc key during startup - with the DVD in the tray - one of the boot messages read:
I/O buffer error in /dev/sr0 at sector 4096
Does anybody know what the problem is?
Update 1: I have done the stuff suggested in How to install all existing media codecs? - only two additional packages were needed. So my computer was already up to date in this regard.
But I now attempted
sudo mount /dev/sr0 /dev/dvd again, followed by

I think "scrambled sector" refers to the CSS encryption that exists on DVDs - do I still need to install something?
Update 2: Using VLC and its "Open Disc..." dialog, now it works. And this:
sudo mount /dev/sr0 /dev/dvd mount: /dev/sr0 is write-protected, mounting read-only mount: mount point /dev/sr0 is not a directory dmesg | tail [ 1378.434161] UDF-fs: INFO Mounting volume 'PLATOON', timestamp 2000/09/24 06:26 (1000)
...but yet, the DVD doesn't appear anywhere. I can't navigate to the DVD.
