Recently I bought some old JAVs off r18.com (sister/English site of DMM), they changed the normal WMP DRM to something else. Now u need a thing call rplayer to view their videos (effective from 1st July 2015). That might have something to do with the the lack of FHD vids .
I think it has something to do with DMM's new rules for downloading clips. Best regards and tons of thanks go to Yipman, for everything you've done for us. You're practically a God.
