Yep, the Patreon client has the ability to decrypt local *.dcv files downloaded from DMM.
Hello, if I download a video from dmm.co.jp (FANZA), but the title is removed from the site at a later date, will I still be able to decrypt the file?
If it's in your library and you have a licence for it (But it was removed from general sale) then yes, you should still be able to decrypt the file. If they revoke your licence as well, then all bets are off.
