I use Nero Burn 6 Ultra Edition to write DVD movie files on DVD+R media. I initially use DVD Decrypter and store the files on my HDD before I burn them on disc. Everytime I use DVD+R media I get a burn fail error message and in the log i see ‘failed to close disc-at-once’ or something like that. However, when I use DVD+RW media I get a successful burn.
What version of nero are you using and what is your hardware setup, drive firmware, media used etc, more info please.
Just so you know the problem is not global, I use the same software with my Plextor 504A DVD+R/RW and Nero Recode 2 works generally well (… i.e., I have only written one coaster onto TDK 4X DVD+R media.)
