Cant backup PS2 game

I have the new DVDFab Platinum and I did buy the Reg Key.
When I try to backup a PS2 DVD, it reads the game DVD but not the DVD I am tring to backup to. I get

“NO media inserted”
“Please insert a compatible media to start the write process”

I have tried plus and minus DVD’s from different manufactors with the same error. any ideas.
I have 2 DVD’s on my puter and have even tried to backup to same DVD drive with the same error. :doh:
