Since the last KDE refresh, the device list shows DVDs not by the DVD label as it always did, but simply as "DVD-ROM".
In this state, applications can't use the DVD. The usual choices are given in the device list entry, but they all throw unspecified errors if you attempt to open then for the disk.
Reverting to a cauldron system from last December, normal behavior is restored.
Blank disks seem to be recognized by k3b, and burns seem to work, but nothing else does.
I've tried rebooting with no success. The error is solid, and occurs with both of the drives I have on the machine.
Steps to Reproduce:
Either the bug has been fixed or else this may be significant...
I logged out of KDE and into GNOME, inserted a DVD, and it was recognized fine. Then I logged uot of GNOME, back into KDE, and the disk was also recognized there. I unloaded and reloaded the disk, and it was still recognized. I unloaded that DVD and loaded another, and it too was recognized.
The true test will be when I can reboot and try it first in KDE.
Looks like this got fixed.
No, it's not. In current cauldron with plasma5, this has resurfaced.
It happens primarily with commercial DVDs. It will happen sometimes with a locally-burned DVD. The Device List popup shows only DVD-ROM, and none of the apps shown in the "choices" list in the popup can open the disk, showing either an error or "no media present".
However, DVDFab running under Wine detects the disk, displays the correct volume label, nd reads it just fine.

can you test with plasma 5.5.3 ?
plasma-desktop 5.5.3 installs fine. plasma-framework gets:
[root@ftglap ~]# urpmi plasma-framework
installing plasma-framework-5.18.0-1.mga6.x86_64.rpm from /mnt/cauldron/x86_64/media/core/release
Installation failed: file /usr/share/kdevappwizard/templates/qml-plasmoid.tar.bz2 from install of plasma-framework-5.18.0-1.mga6.x86_64 conflicts with file from package kapptemplate-1:15.12.1-1.mga6.x86_64
Is that a problem ?
I still haven't got plasma-framework to install, but plasma-desktop is at 5.5.4-1 and this problem still occurs, sort of.
The DVD label still doesn't get read, and the notification display still shows DVD-ROM. However, the various applications are now able to read the disk and show the correct label.
Please update. You should be able to install plasma-framework now.
Yes, I forced it on a while ago. But when I run DVDFab as a wine application (DVD ripper), in many cases it reads the volume label correctly while plasma notifications still only identifies it as "DVD-ROM".
This is with cauldron updated as of yesterday.
Sorry, that should be DVDFab reads the volume label correctly in *all* cases whereas Plasma reports DVD-ROM in most cases.
can you provide a screenshot please ? ( for me to understand better ).
I'll try, but I'm not sure it's possible. The "DVD-ROM" thing only shows up in the notification popup that indicates that a DVD has been inserted, and I'm pretty sure that disappears as soon as you do anything else on the desktop (like request a screenshot).
Just to be clear, you load a DVD; plasma plays with the drive for a few seconds, and then displays the notification panel which shows what is present in each mounted volume. The first is usually the DVD, and displays the volume label of the inserted DVD. In the error case, it displays only "DVD-ROM". However, wine applications which read the drive directly have no trouble reading the volume label correctly.
Probably the best way to debug this is to grep the source for "DVD-ROM" and figure out what error is causing that to be chosen as the default.
The notification popup shows "DVD-ROM" and lists a single available action - open with video player (DragonPlayer). If you choose that, Dragon Player opens, but if you click Play, the icon changes correctly and a Pause icon appears, but almost immediately disappears and reverts to its original status with no error, i. e. it gets an error reading and gives up.
Meanwhile, a wine application is happily reading the DVD.
Is it still valid with latest plasma update?
I just tried this, and it works fine for me in almost-current Cauldron (Plasma 5.8.0).
After inserting a regular DVD-R with a label, the device notifier pops up showing the correct DVD label, just as Dolphin does on its Places panel.
I don't know if this bug is related to movie DVD's, but I imagine it shouldn't make any difference.
Follow-up: Tried with a regular Movie DVD, and the label also appears correctly. In this case, "Open with Dragon Player" also appears, and clicking it works as expected (DP launches and the movie starts playing).
I haven't seen this for a few weeks now, so I'll close it for now.
