There seems to have been info about this with older version of kde but the advice I've had on this didn't solve this minor issue. With Gnome Vlc can start a Dvd that has been inserted, without intervention. What happens instead with Kde is the right-hand devices widget will appear and give four options, one involving DragonPlayer, which I like to avoid as it seems to be easy to jog the film's progress with a slip on the touchpad. I've replaced its mention in System Settings > Advanced > Device Actions with vlc to no avail. Watching a Dvd film with Vlc is a bit laborious at present, unless someone has mastered this? I've also amended File Associations to no avail.

I am using Linux Mint 9 Kde, which uses Kde 4.4.5.

Thanks.

The latest version of VLC ships with actions for the Device Notifier I believe. And it appears that there is a bug in the interaction between Device Notifier and the Device Actions control module, which i'll look into.

Have you tried restarting Plasma to see if it makes a difference?

In the meantime, copy $KDEDIR/share/apps/solid/dragonplayer-opendvd.desktop to ~/.local/share/applications and rename it to "vlc-opendvd.desktop" and change the executable name using a text editor. You may need to restart Plasma after this change.
