I noticed a problem with device notifier: when I insert a DVD it recognizes it without problems, I can click the options and select to run it with kaffeine... but when the movie ends and I click again in the device notifier to extract it (yes, I close kaffeine first), it only gets unmounted: the DVD do not opens. Then, if I extract the DVD manually the device notifier do not refresh so I still see the DVD listed even if it is not there any more.
KDE SC 4.6.5 on openSUSE 11.4 64 bits. I'm sure I did not have this problem with a previous 4.6.x version (don't ask me which one: it's some months since the last time I've seen a movie on this pc... )

The issue of it not updating is most definitely a bug.

I'm not sure why it doesn't eject the disk, I am guessing it just unmounts it but does not send the eject command. This may be a decision taken by UDev or UDisks however rather than KDE.

From three DVDs, with two the device notifier did not update, but with the third it did... None was ejected. I'll watch a bit more this issue. Let's see when I'll get enough time for more movies...
