I need a way to capture lectures(video and audio) from a usb pen drive that only works after installing its software. I have installed it and have access to all the lectures but I am afraid that the subscription is going to expire in short time. I need to capture the videos on my computer and I tried various softwares like snagit. The main video-hosting software from the usb however blocks all my programs and does not allow it. I am really in need of these lectures for my entrance test and will keep the videos private. Can anyone please suggest a software or a method to hide snagit or similar screen recording software from the usb software?
