I bought District 9 from the Playstation Store on my ps3 and I want to put it on my computer so I can put it on a dvd or something. Can someone tell me how to do this?

I just purchased a Playstation 3 a couple of weeks ago. (40GB…I couldn’t find 80GB models anywhere in town) I got a couple of good games for it too. I wonder what good full games are worthy of downloading from the Playstation store.
