When an ISO9660 DVD is inserted in its tray, the new device widget pops up asking to open with k3b or browse the disk.

When a UDF DVD is inserted, either nothing happens, or the new device widget asks whether to open with k3b. It never offers to mount the DVD and browse with Dolphin.

The disk can be simply mounted as root and browsed seamlessly. I found this behaviour on two machines, and I'm wondering whether there's something wrong in my setup. As an additional note, the disk gets simply mounted on Win10.

Can someone please confirm same ?

Thank you.

You can change that in the System Settings -> Hardware - > Removable Storage -> Device Actions

Thanks, I could create an action that will pop up, but the problem is to write the correct 'kioclient exec' command. It should mount the drive and open dolphin on the mount point. Any hint ?
