Have you read any of this thread? DMA needs to be turned on...here is a guide. This is Nero's own packet writing software which tends to step all over itself...I suggest removal via all of the clean tools available at Nero's website. Reinstall omitting the InCD package. Auto burning is not supported with Nero 6 past version 18.104.22.168...why not use DVD Shrink and then burn with Imgburn or DVD Decrypter, they both have booktyping/bitsetting features.
