Comment 1 Dario Andres 2009-09-18 16:03:49 UTC

Mh, this seems to be related to Phonon/Xine. However it could also be related to the implementation in Dragon (or how it should prevent from this to happen, or automatically mount when needed)..

Comment 2 Martin Sandsmark 2009-09-19 17:11:38 UTC

What do you mean “mount” the DVD?

I'm unable to reproduce, fwiw. Clicking on “Play disc” with no disc in does nothing, just popping in a DVD (“Mute Math - Flesh and Bones Electric Fun” fwiw :-), and clicking “Play disc”, without doing anything else, plays the disc.

Comment 3 Etienne 2009-09-20 15:42:45 UTC

I ment that if i first open the dvd with dolphin it worked fine.

Tryed also a different device and that one worked as expected. The problem may be relatet to my dvd-device (Plextor PX712A (Just remember that i had alredy trouble with that device in the past)). 
Also noticed that the working device shows the option "play dvd" in the kde open dialog. It's not the case with the Plextor. 
By the way, if i open the Dragonplayer a second time after the crash it also works. 

So it seams that i just have a special hardware situation...
Well, after all it plays DVD's :)

Comment 4 Etienne 2009-09-28 21:31:21 UTC

Since a week or so, i can't reproduce it anymore:) 
Must have been resolved by an update. 
Thanks for your Time.
