Manually edit Nero's burner settings

Is there any way possible to edit the settings Nero uses for a burner? I know it used to be possible, but I can’t find the file to edit in Nero 6. The reason being, I used a USB enclosure to make my 4x DVD+/-RW into an external, but it won’t let me burn faster than 2.4x. Any assistance you can provide would be greatly appreciated. Thanks.

Bah, never mind. All I had to do was run the “Determine Maximum Speed” simulation. It detects my burner as a full 4x now.
