Which K3b's options should I use to quick format dvd+rw? When I do quick format available in K3b, i get messages that is no need format medium more than once a that it could be simply overwritten. If I do so, k3b keeps adding burned data to previously burned and it doesnt clears dvd+rw.
Ahh, dumb me. Setting multissesion from "auto" to "no multisession" fixed the problem ...
