When I attempt to open .mov files, I receive an error message "The movie cannot be opened. This is not a movie file."
I have tried to open from within QT Pro and get the same message.
Thanks in advance for any assistance.
I wanted to mention that I have the same problem but that I am on SL 10.6.1.
First it told me that QT was not installed.
I uninstalled QT and reinstalled from the SL DVD supplied with the machine (yeah I bought a machine with a new OS on it, will never do that again)
Not it's thinks the application is installed, but I get the Yellow exclamation point window with the message "The movie could no be opened. The file is not a movie."
