Howto use KDE4's device notifier to play a DVD in SMplayer Submitted by tom on 7. February 2009 - 15:45 Just finally figured this one out! It's possible to add an entry to KDE4's device notifier, so you can just click & play a DVD in SMplayer. Awesome! You need a very recent SMplayer and Mplayer, latter one compiled with dvdnav support.
