Well I am not sure what we seem to be debating here.

1. he has RW DVD with old content, he wants to wipe/erase/reformat 
whatever to reuse it as a blank DVD
2. using K3b and the menu Tools/Format-Erase K3b does something and then 
ejects the DVD
3. on reinserting the DVD the system does not react to it
4. if taken to a windows system and same procedure done by whatever 
software DVD is again reacognised by Kubuntu

I have no RW DVD so I can not do this at the moment but I have several 
times done it with CD RW discs without this problem. When I reinserted 
the CD my Kubuntu would recognise it and the device-notifyer give me 
some action options (Dolphin, K3b and so on)

So, as I understand it, the problem lies in that K3b does something 
to/with the DVD RW that disables Kubuntu recognising it
