Thanks for your answer.
The project with 15.33 GB left, the resulting volume is 33 GB (35,497,362,940 bytes).
After that, I burned the volume with CyberLink Power2Go and the Sony BWU-200S burner to a 50 GB Blu-Ray dual-layer disk from Sony.
It plays verry well on my Playstation 3.
For the project that was too big, the image was never maded, after the message "too big" the making of the image was canceled.
