I have downloaded a couple games and would like to know what files to burn and what kind of dvd i need to burn them as. Please help. Thank you
Unless someone took the time to properaly crack & rebuild a console game you should avoid those kinds.
Otherwise use Imgburn to burn disc images and you can use either + or - R for games. Xbox uses +R for its games, video DVDs should also be +R. So just go with +R.
