As dballs said, it seems that it is not a problem with Nero. When you select the option Recorder --> Choose recorder in Nero, do you see any recorder to choose? If you don't see any recorder there, it seems that the operating system does not recognize your recorder. Can you read CDs and DVDs in Windows putting them into that recorder? (My Computer --> D: or E:). Maybe Windows does not recognize the recorder...
In my opinion, using a new program (like Alcohol) will not help in your problem.
