I just loaded up Kubuntu from the 12.04 LTS desktop DVD media in order to use k3b for Blu-ray data burns with cdrtools.

k3b keeps causing a notification for "Extra packages" -- even though the packages in the notificaiton have already been installed.
I burned one disk successfully and k3b can no longer detect media in the burn menu.
If I use the media info menu item it sees a blank disk just fine.

It would really be great if I could get some of this to work :/
