Since this is in the how-to section for future reference it should be posted that if it is a computer game then all you need is a screen recording program such as Camtasia, this will allow you to record the audio and video of both cutscenes and gameplay, but if the game is on a home system then you will need a video capture card, or any video card that also offers video-in capabilities, seeing as how I have never used one I will allow someone else to elaborate on the process of using one of those since I'm sure there is a better way of capturing the video from that rather than using something like Camtasia.
