Have you already tried the LBA 45000 trick? Maybe if you were to put some of the files which don't get streamed in session 1, you could easily bypass the protection with a minimum of quality loss. El Bucanero's rip database doesn't mention any special protections, but then again, the database isn't very reliable IMO.
Whatever you do, good luck with your release.
Thank you for your help, If I put the files in the first session I am without space in the disc, I'm not downsampled nothing, I riped perfectly all audio file, in the disc 1A I removed all audio files not used.
At the moment I am very busy translating frame gride, soon I will work it again.
