Video files problem

When I open my Nero Express after adding all vob files and start to burn them into DVD, error message appears with "DVD-Video files reallocation failed. The resulting DVD-Video
might be unplayable. Do you want to continue". Then I quit the program and start again but with same result.
Followings are the findings of the log prepared for your easy reference :

I don't know what has gone wrong and hope you can advise what remedy action I have to take now in order to enable the burning process can be properly carried out.
Thanks for the assistance provided !

 

Are you adding the VIDEO_TS folder to the job or individual files in the folder.
