If you want to play the files only (and not burn) Get daemon tools lite, which is free. You can use this to "mount" the .iso file, which is the equivalent to inserting a CD or DVD with the data contained in the .iso into a virtual DVD-drive.

To do this:
1) First install the program (and reboot like it tells you)
2) then once it's installed you mount the image by right clicking on the daemon tools lite system tray icon and choose mount image, then browse to the .iso file you downloaded using your bit torrent software.


Or, if you just want to burn the .iso to a physical CD/DVD use burning software like Nero or ImgBurn (freebie) to burn the image. The image is the .iso file.
