I think you may try another better burning software to help you , nero is good at burning data dvd not video dvd ,and have error on my computer when burning video dvd , maybe you can try RZ DVD Creator , now i am using it , works well , it can directly convert any video files to standard video DVD and burn to any DVD disc(DVD+R, DVD-R, DVD-RW, DVD+RW, DVD-DL, DVD+DL, etc), such as mp4 to dvd, the burned DVD can be played well on standard DVD player. you can yahoo or google search and download RZ DVD Creator, easy to use, good quality, you may have a try!
