Yesterday I insatlled a Hitachi DVD-rom drive into my iBook and all was going well until I tried to use the drive. Whenever I play a DVDwhether I'm using apple DVD player, VLC, or mplayerthe drive spins at a very fast speed and does so until I stop playing the DVD. There is definately something wrong because I am able to hear it over my headphones at mid to high volume. Does anyone know how I can fix this? Thanks.
