Medium present not present

Hi,

When I start K3b with a blank DVD+R disc in my DVD burner it show no
medium present. Then after a while it shows information about my
medium. But then it goes back to the state where it says no medium
present. It continues like this back and forth and never seem to stop.
What might be the cause?

I am using K3b 1.0.5.
