I think I know what you mean, mine does that when I use a W7 install disc. It's like the drive is spinning so fast it sounds like a vacuum, the laptop vibrates as the disc is not balanced.
Is this what you mean ?
Other times it continuously scans the disc and never stops, but that may be normal, for when it stops the movie pauses until the disc scans again.
