There is a Fraps alternative called WeGame Recorder. You can get it here http://www.wegame.com/download/
but you will need to make an account first. I have used it for ages and is very good. Once installed, I would reccomend going into settings, screenshots and select "manual uploading" so everytime you take a snapshot it doesn't upload automatically. If you want full quality recording you need to be a VIP Member. You can get hold of the full version of Fraps for free but I'm not entirely sure if it's legal.
Hope this helps
