Activate the checkbox which allows overburning and specify the maximum CD length. In theory you can choose any size up to 99 minutes and 59 seconds. Initially you should enter a length 2 minutes longer than the specified capacity. If SCSI/ATAPI errors occur at the end of the simulation or burning process, we recommend that you reduce the maximum overburn capacity or use a different make of CD. If no errors occur, you can gradually increase the overburn capacity.
This setting will have the following effect on the burning process:
If the amount of data to be burnt is larger than the normal capacity of the blank CD, but less than the maximum overburn capacity, Nero will ask at the beginning of the burning process whether you really want to overburn. If you answer yes to this question, Nero will start the burning process. If you answer no, the burning process will be aborted because there is not enough space on the destination CD.
