gameplay capture

I have a Samsung BD-D6900 3D Blu-ray player, can i record my gameplays with it because my fps drops when i record with a software, please help me!

So i havent really tried using shadowplay but saw people recommending it for recording and sharing but when i press ALT+Z my screen doesnt like just lower its brightness and opens menu it goes full black and SHADOWPLAY doesnt want to start recording.. i have tried in bunch of games but same crap...

This morning my Windows program updated. When I tried to play a video later on it wanted me to choose regular or custom install. It would not let me do a custom so I did the regular install. Now it won't play mp4's and other formats. How can I un-install and go back to my old reliable version?
