    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Preferences/com.apple.quicktimeplayer.plist. Move the .plist to your desktop.


    Open the application and test. If it works okay, delete the plist from the desktop.


    If the application is the same, return the .plist to where you got it from, overwriting the newer one.


    Thanks to leonie for some information contained in this.

     

    You might need to redo the View settings after an update.
