A good way to block this kind of thing is just to use DRM. Most platforms now provide a completely blocked off and secure hardware DRM solution that makes it impossible to grab video frames or view decrypted data in any way from the host operating system or any app running on it.
Ripping the video segments would just give you encrypted and useless data without the license.
These kinds of systems would need to be attacked by HDMI or other downstream hacks, or an HD video camera pointed at the screen in a dark room :)
