Quicktime hangs my system

I have a G4 sawtooth with 1 GB of RAM and an OWC Mercury Extreme 1.2 GHz processor upgrade, running OS 10.3.9. Before I upgraded the hardware, playing any sort of video in Quicktime would hang my Mac (freezing the mouse), forcing me to reset the system. Upgrading the RAM and processor has not changed this, and playing video in Quicktime continues to hang the system. The only thing I have yet to try is upgrading the video card (machine currently has the stock AGP video card with 16 MB of VRAM), but based on what I've read are the minimum system requirements for QT I'm having a hard time believing that this is the problem. Am I wrong? Do you have any suggestions? Thanks.

QuickTime is not hanging your System, QuickTime is your System. As a first troubleshooting move, you should remove any additional codecs that you may have added. Restart. If the problem persists, then you may have to reinstall your OS.

If the problem goes away, then update each codec to the latest version and add them back one-by-one.

It wasn't Quicktime. It was the video card. OS 10.3 apparently doesn't support video acceleration on my aging ATI Rage 128 card. Swapping it with an ATI Radeon 8500 solved the problem.
