DVD mounted without read permissions

I have problems with my DVD drive. When I put a DVD in, it is mounted, but without any read permissions.

I tried mounting it manually, but without success. I am able to read directory structure and files only as root.

Relevant line from /etc/fstab:

/dev/sr0        /media/cdrom    auto    gid=24,user,noauto,ro,exec,utf8  0 0

Mounting attempt:

$ ls -l /mediadrwxr-xr-x  2 root cdrom 4096 zář 12 10:12 cdrom$ mount /dev/sr0$ ls -l /mediad--x--x---  3 nobody cdrom   88 úno  1  2014 cdrom

Output from sudo lshw:

*-cdrom    description: DVD-RAM writer    product: DVD A  DH16AAL    vendor: hp    physical id: 1    bus info: scsi@1:0.0.0    logical name: /dev/cdrom    logical name: /dev/cdrw    logical name: /dev/dvd    logical name: /dev/dvdrw    logical name: /dev/sr0    logical name: /media/cdrom    version: LHDE    capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram    configuration: ansiversion=5 mount.fstype=udf mount.options=ro,nosuid,nodev,relatime,gid=24,utf8 state=mounted status=ready

DVD drive and disc were tested on Windows system and worked. I also tried different DVD drive with same results.

Also physical eject button is not working on Ubuntu. I tried eject -i off, but without success.

Any help would be appreciated. Thanks.
