The DOS based OSes may have issues since the DVD as a disk drive exceeds some 4 GB. This issue has no known cure if you have those OS.
As to the non-DOS Microsoft OSes, you'll make sure the media is DVD+R/W (I hope I remember that proper) and the InCD is not the version that came with the drive. An update may be at the Nero website.
In the future, try to supply the other pieces of info such as OS, media in use, versions of software at play...
I have formatted my DVD RW disc using InCD but when I try to copy files from explorer I get "access is denied" make sure the drive is not protected or in use.
Have I missed a step to write to this DVD like a big floppy?
