I recently bought the KHypermedia KDVRW8X DVD burner and it burns and plays CD's flawlessly but for some reason I can't burn any DVD's or even watch any regular ones. I'm using Nero 6 and Power DVD. I also messed around with the firmware and it made no difference. What about aspi files, under Nero system files it says I'm missing but which one? I have WNASPI32.dll 4.71 WINASPI.dll 4.6 WOWPOST.EXE 4.6 Would this make any difference.
