How to burn games to empty cd off of torrents?

I have just finished downloading the game Batman Arkham Asylum for windows off of utorrent and i need to know how to burn it on to a empty cd|||If you the game needs a CD to run, you can download Microsoft's Virtual CD software, it mounts .iso files so that you can run it without using a CD. If it's not on a .iso file, you can use MagicDisk or someother CD image program and create a .iso file.
