I tried a couple of things but still could not get NXT 4 to do that...
Sadly a lot of good things were dropped
There is still one backdoor approach, didn't try it yet, but it is there!
Create your Project in VideoWave and Export As to a file at the same quality as you want (dvd = 720 X 480 @ 8-9 kbps)
Add that file into Copy & Convert.
Choose DVD for output and don't check the option for Menus
Another benefit of using Copy & Convert is that without Menus, it will be a looping DVD! Disadvantage is that it is limited to DVD
