I've never come across any dvd based game that hasn't burned under nero. I've got 60+ dvdr backups which are all perfect.
But usually the issue isn't down to just the software, it is dependant on your dvdreader, and your pc status overall.
I've recently made the change to recordnow max and it's a change i'm gonna keep. I was curious but the software on a whole seems to work a lot better. Nero always used to ignore my request when i asked it to read the dvd original at only 3x. and used to read it in at 16x regardless on my pioneer 106 reader.
Under recordnow max it reads it at slow speed
Use what works best for you.
