ABOUT NERO DVD FAIL

I M WRITING A DVD AND THE IMAGE WAS COMPLETELY WRITTEN ON THE HARD DISK BUT WHEN I INSERTED THE BLANK DVD IN THE DVD WRITTER , IT STARTED BURNING THE DVD AT HANG ON 91% AND IT WAS NOT GIVING ANY ERRORS AND I RESTART THE COMPUTER,THE DVD IS NOW NOT PERFORMING TNE OPERATION. BUT ONE OF MY FRIEND IS SAYING THAT PUT THE DVD BACK TO THE DVD AND BURN SAME PROJECT BUT IT DOES NOT WORK.

IS THERE ANY WAY 2 HANDLE SUCH PROBLEMS.
