Symptom:

Since a few days i had an Problem with playing selfmade DVDs. CDs (Audio and *.avi) can be playes. Original DVD’s too. But i have made DVDs with an DVD RECORDER (for TV). Then i burn 2 Movies on the DVD and the Recorder makes an own Menu for the Movies. But if i insert the DVD to the DVD Player, the Device Monitor sayd me, the only three Alternatives are: open in Dolphin, open with Digikam and do nothing. If i choosed Dolphin, dolphin startsand then i see in the bottom an Red Line with the Error “No Access”.

First tries:

I listed the Directory:
lrwxrwxrwx   1 root   root          3 10. Apr 15:24 cdrom -> sr0
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 cdrw -> sr1
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 dvd -> sr0
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 fb -> fb0
brw-rw—-+  1 root   cdrom         11,   0 10. Apr 11:45 sr0
brw-rw—-+  1 root   cdrom   11,   1 10. Apr 11:45 sr1
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 scd0 -> sr0

lrwxrwxrwx   1 root   root          3 10. Apr 11:45 scd1 -> sr
My User is in the Group “cdrom”.

Then  i’ve checked /etc/udev/rules.d 99-my.rules:
There i found: KERNEL==”[sr*[0-9]”,GROUP=”cdrom”,MODE=”0660″

getfacl /dev/sr0 says:

getfacl: Removing leading ‘/’ from absolute path names
# file: dev/sr0

# owner: root

# group: cdrom user::rw-
user:sascha:rw-
group::rw-
mask::rw-
other::—
For sr1 its the same output.

Then i go to  /usr/share/PolicyKit/policy/org.freedesktop.hal.device-access.policy and set the following:

</action>

Then i made an reboot, but nothing happens. The same Error is
present.

Today i found out, that all non accessable DVD have the following
Rights:
dr–r–r–  3 sascha 4294967295   88 15. Okt 2006  DVD_VIDEO_RECORDER/
^^^^^^^^^^^^

Strange permissions.

SOLUTION:

Then i created an File in /usr/share/kde4/apps/solid/action with the following:

[Desktop Entry]
X-KDE-Solid-Predicate=[ StorageVolume.ignored == false AND OpticalDisc.availableContent == ‘Data|VideoDvd’ ]
Type=Service
Actions=open;

[Desktop Action open]
Name=Play DVD with video player (Kaffeine)
Exec=kaffeine -d %d DVD
Icon=kaffeine

After an relogin, the new Alternative are present. I can go to open with Kaffeine, and than we have finished this task.

BTW: Please check if KDE3/Kaffeine is installed. Without them the Workaround will not work.
