What version of Nero are you using ?
If you still use an older 5.5.x.x, it could be that that version is too old to know your burner. In this case, update to 184.108.40.206 (available www.nero.com)
In case you’re using an early Nero v6.x.x.x, first try updating to 220.127.116.11.
In case you’re using a recent version (18.104.22.168 or 22.214.171.124), there is probably something wrong with the installation of Nero. Uninstall it completely, use the tools from www.nero.com to clean up both all “nero files” and your registry.
After removing everything from Nero, reboot and reinstall the current version.
This should work.
