Game dvd isn't detected

Can you try the "sudo mount /dev/cdrom /mnt" and paste the output here?

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type

Ok try one of these commands:

  sudo -t iso9660 mount /dev/cdrom /mnt
  sudo -t ufs mount /dev/cdrom /mnt

If none of them works it will mean that either the CD is corrupted or burned in a format I cannot imagine!

Well I tried both and got the following
usage: sudo -h | -K | -k | -L | -V
usage: sudo -v [-AknS] [-p prompt]
usage: sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U username] [-u
            username|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
            username|#uid] [-g groupname|#gid] [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
            username|#uid] file ...

I know that the dvd has an autorun.exe file(I checked it on a windows 7 laptop).
Please help,I really like ubuntu 10.10 I really don't wanna go back to windows but if I can't play my favorite games I'll have no choice.

Thanks Manfred Hampl, that solved my question.

Sorry for that!
