I have that issue also. I update 3 out of my 5 Macs that run 10.5.1. All did what you are experiencing. I had to go back to 7.3.1 and the issue went away. It's a problem with 7.4 Quicktime and Apple is aware of it. You have to use Pacifist to install 7.3.1 QT but it can be done. Here is a URL on the Apple Discussion Forums. I followed the instructions in a post there using Pacifist and was able to go back and play my many MP4 files.

Good Luck.
