I am the unlucky owner of the SONY DRU-530A. Its great for burning CDs but does not burn any DVD I have tried. I have tried DVD-R and DVD+RW media and it says it has the wrong disc type after transcoding. - I burn using Nero I have downloaded the latest firmware. I have disabled DMA Reading other forums it seems this Rewriter is no good. Does anyone know how to make it work - or can anyone recommend a rewriter that is as quick but more reliable to burn DVDs using Nero.
