All the video files of MadeEasy are encrypted by the http://www.gameofcourses.com they release their custom player called ‘goc’ aka gameofcourse player which generates the unique machine code when you open their video player and it ask to visit their site to purchase a private password key (decryption key according to the machine code of individual devices).
This password will not work cause it was only generated for the one device based on the machine code. Every device has different machine code according to the goc player. They have implemented their custom encryption algorithm to generate the machine code (encryption key) and it can only be decrypted by them.
Unless someone reverse engineer their player to bypass there’s no way to play the videos cause you have to buy the key from them.
