I have an ATI video card installed and have the Catalyst 12.4 video drivers installed everything has been working fine until I updated my system on Tuesday. Now when when I try and play videos the whole system freezes after a few seconds. I end up having to reboot the machine each time. The system works just fine up until this point. This is the list of all the updates I did:
