Have you checked to make sure that you have done all of the other updates through software update? Also, you might want to see if you ahve upgraded to the latest version of quicktime (which is 5... I don't think that this makes a difference, but it's worth a try). Also, try running disk first aid, or some other utiity, and also try defragmenting the disk...
let us know if you resolve it...
