When I put a dvd in to the drive it very rarely works. It usually just makes a bunch of noises, which sound like the eye in there jerking back and forth and having a seizure

. Sometimes when I put a disk in it will make the noises for about 10 or 20 seconds then just stop and act like there is no disk in there. If I eject the disk and put it back in 5 to 10 times it will eventually work

Any help would be greatly appreciated.
