R18 DRM decryption works like a charm.
how about sokmil? is it possible to decrypt the DRM? and will you develop it in the near future?
Interesting! I suppose this might be something I can investigate if I get spare time. Perhaps maybe figure out what the next largest/popular website is and look at that as well? Maybe if there is a top 10 list of the most popular JAV website (aside from R18/DMM)? Unfortunately, the demands on my time are considerable, so I need to prioritize this with my backlog of items. Naturally, I need to focus on tasks which benefit the most users and Patreon members first. (^_^);
Did you figure it out? Just need to open the red box and it will show a drop down menu for the downloads as this picture demonstrates.
All the videos you purchased should be shown in the my page/my library 
Some videos aren't available on dmm/r18, and so I purchase them on the other websites and use OBS to screen capture. I don't really have a great computer or anything, but the quality is just fine to me as long as you allow buffer to prevent jittery stutters.
