Suggestions Required!

Hi Tech Frnds! I just want to know whether i can recover my data from a scrathed DVD or not... Actually i have a DVD of Vegas 2 Game and due to a little scratch..setup is not accessible and i am unable to install the game... So, is there any tool or tech tip to run that DVD or transfer that data into PC.... Secondly... Is Gears of War is compatible with Windows 7 or not.......!! Waiting for Suggestions!

First clean the DVD with a soft cloth and then use UltraISO or any other sofware like that to make an image of it. I am sure that it will work 99.99%.
