I have a Question

I got a new jtag last week with the freestyle (ive only used XEX before) and I want to know how I can download games and play them on my xbox :?: ie. MW2. I own the game too ifthat helps, and I believe I also have the correct torrent file downloaded. Ive tried Putting it in the games foder, and content folder but they only show up in file manager, not on the place where you select which game to paly. Do i need to extract the files with somthing other than bit zipper, or am I just doing somthing wrong? Thanks!
