Hi (again)

Firstival i must tnhak you for the advise of buying a cd cleanner, i bought one for dvd drives and it worked, because after using it i tried my dvd backup and it played normally, but after playing a game i tried it again(to be sure that everything was ok) but it didn't worked like before
So i used the cd cleanner again and it worked, i think it's kinda weird!! Do you anybody know why this happens!!
