Can I record this to a video file? please help
 

Is there a software or something that allows me to record all the actions I do on my pc to a video file? like when playing a game can I record the game I'm playing to a video file?
I know you can do this by having a video card that supports tv output and then record it to a VCR but the quality is poor it looks blurry.
I need this to record a tutorial of a game for a friend.

Thanks.:)
