K3b can't see DVD

I have latest k3b from packman installed. It works fine when writing to CD.
When I want to burn a data dvd, it doesn’t see the empty media and thus I cannot burn. The system does see the media (indicates on toolbar down below) as a blank DVD.

what is the message when it exits burning?

There is no message other than normal, - it asks for you to put in empty or appendable disk, and when you do, the message stays the same, even though my media indicator on the toolbar shows that an blank dvd has been placed in the DVD writer.

strange… maybe try and downgrade your version of k3b and see what happens?

I will try in the morning - the machine is at work. I will report back tomorrow
