Have you tried downloading the latest KEYDB.cg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?Bruce Leroy wrote: ↑Thu Jul 17, 2025 4:35 pmJust got in my Shout Factory, Ace Venture Pet Detective 4k Steelbook. Here's the dump file, for failed decryption. Appreciate the help. Cheers!
Oh man, thanks for the link. I was just searching for the download link. I have several movies that still need decrypting. Zombieland UHD (Steelbook), Clueless UHD and Ace Ventura. I'll following if this link works.MrPenguin wrote: ↑Thu Jul 17, 2025 4:43 pmHave you tried downloading the latest KEYDB.cg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?Bruce Leroy wrote: ↑Thu Jul 17, 2025 4:35 pmJust got in my Shout Factory, Ace Venture Pet Detective 4k Steelbook.

Very nice. the updated KEYDB.cg file worked for both Ace Ventura and Clueless. My Zombieland UHD (Steelbook) still won't decrypted. Nearly been a year now.MrPenguin wrote: ↑Thu Jul 17, 2025 4:43 pmHave you tried downloading the latest KEYDB.cg file, copying it into MakeMKV's data directory (i.e. where MakeMKV also writes its TGZ dump files) and restarting MakeMKV?Bruce Leroy wrote: ↑Thu Jul 17, 2025 4:35 pmJust got in my Shout Factory, Ace Venture Pet Detective 4k Steelbook.

Thanks for the dump
. Unfortunately, "Zombieland" is one of those rare titles that uses AACSv2.1 instead of AACSv2.0. MakeMKV has actually made a conscious choice not to support your "CC8A" disk variant yet, for fear of revealing to AACS-LA which AACSv2.x key it is currently using 
. AFAIK KEYDB is in a similar situation, although the Open Source libaacs library doesn't support AACSv2.1 decryption yet either.
