Or open it with xiso and FTP it over to your xbox...
Or open it with Alcohol 120%, so you don't have to duplicate the files and FTP it... that way it stays an ISO... saves space on your PC.
Or you can use XBMC to create a network share on your PC for your xbox and just drag and drop it.... you can also stream movies and music this way... that way if you have a 120 Gig drive it can all be games and all your music and movies can be pulled from your PC.
Or you can go rent the game... it's only $5 and you know it's a good copy with the right region
Or you could...
Well, you get the idea.
Oh yeah, and.... AAARRRR!!!
