Ever since the introduction of the new decryption some films won't work properly when backed up to BD-r's or bd-re's. Point in case, when I try to back up my copies of Pirates 1 and 2, with version 6.1.5.5 I can decrypt the disc to harddrive then copy over the certificate folder. If I then write this back to a Blu-ray disc it works fine on my PS3, but if I use the newer versions that remove the need for the certificate folder they don't work when written back to disc, either with or without the certificate folder
