Is this a component that comes already installed with QuickTime, or one that needs to be added? In other words, did this work before, and now it is not working?
You could try using VLC Player instead. It seems to play more types of video files without additional configuration, compared to QuickTime Player.

How you can said that it is lost until you check whether its running on other general account in your mac.
Sometimes simple restart from menu do the work.
I had some, i copy that component from another account to shared account to my administrator account.
