There must be a sort of new protection that make your wonderful decrypter to fail in reading the structure of the disc (either in filemode or isomode the things go wrong). Error mainly is "eaccessviolation".
The protection consist of a false starting chapter on the ifo structure (those 00:00:00:00: with layer break).
Look at the ifo here:

Title Set (Movie) attributes:

this is the structure of the VTS_04_0.IFO (main movie) of "THE PASSION OF THE CHRIST" PAL DVD REGION 2.
In this particular DVD there is also VTS_05_0.IFO with the same strange structure. But the corrisponding VTS_0*_0.BUP file is correct.

I notice that sometime the corresponding VTS_0*_0.BUP structure is correct. But not always.

I would ask you if there is a way to tell DVDDecrypter to ignore the facked chapter at the beginining of the ifo structure in order to overcome this protection.

Thank you in advance.
