If you have any non-standard QT plugins /components installed on your laptop (ie, Perian
http://perian.org/), then please remove them at this time.
You can use this handy apple utility to do this procedure:

If this doesn't help, then please call apple support directly. Speak to level one and request a case number from the beginning..... if they can't help you resolve this quickly; then ask for a level two tech and make certain to confirm your case number on this issue. Your case number is considered confidential information between you and apple only. Please do not disclose this number / info on apple discussions and forums. Hopefully we can resolve this quickly.
