Not too sure about DVDecrypter but Nero automatically will choose DVDrom if you have that app installed.

chrome

You’ll find it under option tools there you can see options like settings, drive etc.
Your option is in the drive options.
Also if you write an image you could see a little book right corner for the booktype
settings.
