well, I know that some of these groups used to use
screen recorders, but i am 100% now they don't because I was surfing the onepiece official funimation streaming site, as soon as the new episode was released on funimation, exactly 5 minuted after funimation, horriblesubs released onepiece's new episode, so it can't be screen recorders. Regarding rtmpsuck and rtmpsrv, no , I didn't try using those, actually I don't know what they are, do you know how to use them? thank you for your reply
