Problems with burning dvd's and daemon tools

[rajicb]

After instaling the new daemon 4.06 i have a problem with burning dvd's. I burn the dvd and nero verification indicates that everything is OK, but when i try to use the dvd it is not recognised (wrong drive, insert disk bla,bla...).
I tried 5 times with diferent manufacturers of dvd's same results.
reinstaled daemon, dvd drive, nero and nothing.

What do you burn? You do know that Nero is NOT suitable to create backups of media protected by recent protections?

but when i try to use the dvd it is not recognised (wrong drive, insert disk bla,bla...).

Does this error came from Windows?
