DVD drive spinning discs and making a funny noise

Mac Book Pro Super Drive would load a game dvd and play it, but after a few plays, the drive would pull the disc in when inserted and then spin the disc and make a strange brrrrrrrrrrzzzz.. sound and spin the disc some more before finally ejecting it. I have experienced this same thing with two different game discs.

Has anyone else experienced this problem before?

it plays other discs fine.

thanks for any help
