DVD DL won't burn on DVDFab Gold

I have no problem with 4.7G DVDs but hardly any DL DVDs that I burn work. The 2016 error comes up straight away when it starts to write. Anyone got advice.

deanobravo… What version of DVDFab are u using? Try version Platinum and use the clone mode to burn your DL disk. I have backed up several DVD’s and this way and they are perfect. If this works then try the full disk mode and see if that works.
