Just because a personally recorded CD â€˜Appearsâ€™ to play 'Properly' doesnâ€™t mean that the burned CD doesnâ€™t contain any â€˜Errorsâ€™. Have you closely reviewed the N e r o burning log for a reason why you are receiving the "Burning Failed" notification?
Have you used N e r o CD/DVD Speed (http://www.cdspeed2000.com/files/NeroCDSpeed_47716.zip) and performed a ScanDisc surface scan of the particular suspect "Burning Failed" CD for Errors? A correctly recorded CD/DVD should not have any Red (Bad) and/or Yellow (Damaged) sectors.
Have you ensured that your undisclosed DVD Burner has the newest most current up to date Firmware that is available installed?
Are you using known proven quality error free Media?
