Some software clears it after decryption (libaacs does), some not (I believe MakeMKV does not, but it was a long time since I've last checked). Search http://git.videolan.org/?p=libaacs.g...libaacs/aacs.c for 0xc0 to see what I mean. Those obviously will generate a lot of differences in decrypted files.
