Firstly, download VLC Player to deal with your Mpeg4 video.

If Q'time can't play an mpeg4 file, it suggests that the file itself may be corrupted. Using VLC may show that.

Repair permissions, preferably using the correct version of OnyX for your OS, to see if access to Q'time is restored.

Please post your Mac (or other) specs and MacOS version in your post, your profile or your signature. It helps us to help you better.

I'm leaving now to go and find myself. If I should return before I get back, please ask me to wait.
