Just brought some blank rewritable DVDs (Maxell 1-4x speed, 4.7GB) to write some stuff I have on it from my PC, but when I try to burn using WM, i get an error report telling me that it is not possible. Anybody here know where to go from here?

Might not be the case with RWs, but with DVDR's you have + or - variations, which only work in the respective dvd+rw or dvd-rw drives.
