Concerning the differences in the MKBROM.AACS files. I am wondering which parts of the MKBROM.AACS file differ from movie to movie (or from disc to disc?).

The most important part (for us here) is the Verify Media Key Record. In my MKBROM.AACS its at position 74h (just before the Copyright text):

Code:
00000070: xx xx xx xx 81 00 00 14  87 B8 A2 B7 C1 0B 9F AD 
00000080: F8 C4 36 1E 23 86 59 E5  xx xx xx xx xx xx xx xx
The bolded part is the actual Verification Data (for the Media Key).

I am now very curious if this part if different for other movies. Or if some movies have the same one. So if somebody could check. That would be great .

PS. The start of the MKBROM file is probably the same for everyone: 10 00 00 0C 00 04 10 03 00 00 00 01. The last four bytes represent the version number.
