If you cannot wait, navigate to the VIDEO_TS and try double-clicking the smaller *.ifo files and watch on your PC (VIDEO_TS.ifo I think). Windows Media Player usually works but I use a prog called VLC.

Back to your question....."..

From memory with Nero Express only it was something like....

Use the "Create Video DVD" option. This would open a box with a pinky/red VIDEO_TS icon in it.

You do drag the contents of your VIDEO_TS folder into the Nero version. You can also drag the full DVD_ROM folder into your Nero box alongside the pinky/red VIDEO_TS folder. This will not affect how it all works but it is what the creator intended you do.

The AUDIO_TS is redundant......

Basically your file structure in the Nero box needs to match the file structure of the files on your PC. Then burn. The standard settings in Nero in the "Create Video DVD" option usually tended to work for me.......
