As tazdevl suggested, it won't hurt to upgrade to the latest versions of Nero and InCD from Ahead's site.
Could you tell us the brand and model of your burner?
Your problems with the "another" disc might be due to poor media, or rather to a mismatch between your media and burner, since you can read the disc in a CD-ROM drive. BTW, have you installed EasyWriteReader for reading InCD discs on your CD-ROM drive?
Perhaps your problems will disappear once you switch to better media. Otherwise, we will need more information about your system, as explained in the guide

Don't let it scare you away; just follow the pertinent steps and come back with more information.
