Using Pacifist to downgrade QuickTime
Since I often need to use this information for reference, I am posting a guide here. As you may already be aware, certain versions of QuickTime can cause havoc with Final Cut Pro and other professional applications like After Effects. For example, many users of FCP 4.5 HD have been unable to capture long clips after installing QuickTime 7.3 and up.
Apple does not offer a means of uninstalling a rogue version of QuickTime so the solution is rather "hacky". It will solve the problem but for best results, you are recommended to perform a full Erase and Install to reinstall Mac OS X.
Also, don't perform this process unless it is absolutely necessary.
which version of QuickTime works best with your software.
the version of QuickTime you wish to downgrade to.
4. Start up Pacifist and drag the QuickTime package
onto the Pacifist logo in the main window.
5. A new window will pop up. Use the disclosure triangles to select the following two directories:System/Library/Components
It might be worth backing up the existing /System/Library/Components
directories on your hard disk before performing this.
6. Now click Install
up the top.
7. You will get this message, click Install
and then type in your admin password:
8. It will spend a minute or so extracting and verifying files then this message will appear:
Click "Don't ask again for this installation"
and then hit Replace
9. When it finishes, restart your machine. If you go to QuickTime Player, it will still say the version number of the old version but if you open Final Cut Pro, it will now work as it did previously.

Erik Smith sent me another solution
to the issue, although I would definitely say try it at your own risk.
