Xbox360 Game doesnt work?

I left my Battlefield bad company lying around by accident and by dog trod on it leaving it with a rather noticable deep scratch, as you can imagine it doesnt work. Luckily i backed it up on my pc as i do all my games, but with this game, the burning is fine and i have even run a check with dvd mulleter just to make sure and it says all the game files are fine, Iam also using Verbatim discs, Yet when i put it in my xbox360 it says unplayable disc, but when i put it in my pc it says please put in xbox360 to play, it has done this twice now, Please help me i dont want to have wasted �40
