Setting Nero To Burn D/L

How do you set Nero (and what module) to burn D/L disc?. I have searched in Nero’s every module and I can’t find any clue how to set the burning process for D/L burning dsic.

It recognizes automatically the DL disc, you can select the size before burning,
where you drag&drop the files, bottom right corner between dvd-5 and dvd-9, that’s all!

Thanks for the information, I will try that and report the result later.
