Guys, TOP wasn't asking about what software to use to burn a DVD. He is talking about a physical problem with the drive.
borc4cy, it sounds like you may have a dead laser in your drive. Optical drives use two different laser assemblies; one for CDs and one for DVDs. It is quite possible for one to stop working while the other one is just fine. Since it's in a laptop, you may have a tough time repairing or replacing it on your own. Is the drive a module that you can remove from your computer and replace with another one? Is your laptop still under warranty? Can you still read DVDs (like play a movie)? If you can't read DVDs and it's not under warranty and it is a removable module, your best bet is to go online and find a replacement drive to buy. If it's not a module, you might have to take it to a computer repair shop, or a hardware-saavy friend who's willing to attempt a replacement. Laptops are pretty tough things to mess around with successfully.
