Do you see my happy dance? I fixed my computer! Just did an Archive & Reinstall of the OS and everything came good. I then re-downloaded all the updates and patches and applied them all. (I used the combined update to take my system from 10.3.5 to 10.3.7.) Everything works great. The video problems are fixed as well as my Firewire issues with the iPod. I guess my original 10.3.7 was just a bad update!
