Troubleshooting linux #1

Recently I was trying out Digit April 2009 DVDs on my openSUSE 11.1. After checking out a DVD, when I tried to eject it my taskbar froze and the plugged in devices popup remained on top of other applications.

However, KRunner was working fine so I fired up Konsole and entered super user mode with the following command.
su
After that I started investigating with the following commands.
df -h
ps aux
The DVD was obviously mounted. So, I tried to unmount it using the following command.
umount -v /media/Digit-April09DVD
The message told me that the device is busy. So, I checked the output of ps command keenly to locate what could be keeping the device busy. I found some kaffeine instances:
phoenix 6015 2.7 4.6 518808 47192 ? Sl 18:24 0:40 /opt/kde3/bin/kaffeine /media/Digit-April09DVD/Entertainment/Videos/ComputerGames/Computer1984_4_256kb.mp4

phoenix 6081 0.0 0.0 0 0 ? Z 18:33 0:00 [kaffeine]
So, I promptly killed them and then ejected the DVD manually.
