BleepingComputer.com: DVD burner wont' burn anymore

It won't burn anymore. The past 3 dvd's i tried burning. I know I'm doing it right, I've done this a million times, there is something wrong with the drive or something (not wrong with me). I'm burning an ISO. I've tried using Nero 7 Ultra ISO burner and DVD Decrypter to burn. Nero errors out and Decrypter just sits there at 0% with 100% buffer.
The ISO is no longer protected, so it burned correctly. If I burn it on another computer, it works fine.

Some things you can try:

• If you recently installed some burning software, uninstall it.
  
• Use the fix given on this Microsoft page.
  
• Use a different brand of CD/DVD.
  
• Clean the laser using one of those drive cleaning kits (or if it is a laptop, carefully wipe the laser with a soft dry cloth).
  
• Open the Device Manager (Start > Run > type "devmgmt.msc"). Locate the CD/DVD drive, right click on it and select "Uninstall". After it has uninstalled reboot the computer (it will be automatically reinstalled).
