BlurayTestAndDecrypt - tool to test bluray files and remove AACS

FindVUK seems to check every m2ts file on the disc which it thinks is encrypted to see, if it can be decrypted with the (or one of the) unit keys.

I never made a disc backup with BTAD. My (encrypted) ISOs so far were made with DIC or DVDFab. But of course I tried it (when DumpDrive&Test was the correct option). Here's the log entry for the sectors, where the file is in:

22:12:30 - Read Blocks >     100/15908448< Pct >  0.00% - Speed 0.06MB/s during last >100< Blocks
22:12:50 - Read Blocks >   79600/15908448< Pct >  0.50% - Speed 7.94MB/s during last >79500< Blocks
22:13:00 - Read Blocks >  159100/15908448< Pct >  1.00% - Speed 14.77MB/s during last >79500< Blocks

and the log of the test afterwards for the file:

Filename >\BDMV\STREAM\00504.m2ts< Size GB >  0.00< Unit_Enc >       0< Unit_Unenc >       0< Unit_Err >     22:37:00 - Filename >\BDMV\STREAM\00504.m2ts< Size GB >  0.00< Unit_Enc >       0< Unit_Unenc >       0< Unit_Err >      90< Duration >0:00:00< TSTA

Besides, it's really difficult to see any errors even happening... at first I overlooked the 90 there:

Found another ISO having the problem. Terminator 3 this time:

11:26:47 - ++  COPY  ++ Pct >  9.67%< StartBlock >01798421< BlockLen >00000011<
11:26:47 - ++ DECODE ++ Pct >  9.67%< StartBlock >01798432< BlockLen >00000513< File >\BDMV\STREAM\00273.m2ts<
                                                                                                                                    Filename >\BDMV\STREAM\00273.m2ts< Size GB >  0.00< Progress >1/1<

11:26:47 - ERROR! Unencrypted unit has errors! - stop now

the m2ts file is 1MB in size. And just like with the other disc, creating a backup with DVDFab tells about a read error when making an unencrypted backup and no read errors with an encrypted backup.

When ignoring all errors, it's only this file which has "bad" sectors:

2023.05.16-11:43:43: read file BDMV\STREAM\00273.m2ts error Sector = 1798432  
2023.05.16-11:43:43: read file BDMV\STREAM\00273.m2ts error Sector = 1798464  
2023.05.16-11:43:43: read file BDMV\STREAM\00273.m2ts error Sector = 1798496  
2023.05.16-11:43:43: read file BDMV\STREAM\00273.m2ts error Sector = 1798528  
2023.05.16-11:43:43: read file BDMV\STREAM\00273.m2ts error Sector = 1798560  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798592  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798624  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798656  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798688  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798720  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798752  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798784  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798816  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798848  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798880  
2023.05.16-11:43:44: read file BDMV\STREAM\00273.m2ts error Sector = 1798912

Kinda looks like RipGuard/ARccOS on a BluRay. As encrypted backups work, I would think, that the file seems to have data which causes a program error upon decrypting?

Is RipGuard/ARccOS possible?

1)

When converting a Pavtube BD+ table, BTAD 0.94 puts the FUT in bdplus/convtab/MK*.bin and is able to use it immediately. But when checking for existing tables (supposing the Pavtube table is deleted after conversion) BTAD still expects the old conv_tab_DiscID*.bin filename and isn't able to find the previously converted table.

2)

Printing the BD+ details seems to be broken now, unlike in recent versions of FindVUK.
