Hi,
I have burned several Blu-ray and standard DVD through Nero and ImgBurn utilizing PD9 Ultra folder.
I don't know what version Nero you have I have the Blu ray version. Here is how I do it.
Open Nero rom and select DVD-Video (not DVD-rom), a screen opens with a New compilation in right hand window with a 'New'
as the name and under that there are two folder Audio_TS folder and Video_TS folder, on the right pane navigate to your directory containing the files created by PowerDriector when you save to folder. Now drag the Video folder in that directory to Nero's Video_TS folder, Audio should be empty but you can drag powerDirector audio folder to Nero's audio folder. Now under those you should have your VOB and Ifo Bup stuff.
In root where 'New' is F@ and rename as you want then click 'burn' supplying the drive letter pertaining to you burner, select the speed (not Maximum) and apply sit back and wait.
This works for me everytime
