I have also burned for Blu-ray using Encore cs6 but for some reason it stopped with this error message.
I also saved the project as an image file and tried to burn it using toast with the same problem...
I have mislayed my premier pro cs5 disc for mac if i could find it I would go back to encore cs5.
I have searched every where with no joy..
I have destroyed more blu-ray discs and still scratching the head
