Kirk, thanks for trying, but this is 100% most definitely a serious issue. I broke my own rule about sotware updates. Normally I test on a non-essential mac and then deploy to the rest if all is ok, but this issue was/is a REAL shocker! I kicked myself for doing this update because I lost 3 days of work over it and 3 days of downtime on my podcast. Apple Quality Control - WAKE UP!!
For those with Tiger instead of Leopard I'm adding the URL's you need to download Pacifist and QuickTime 7.4.1 :
QuickTime for Tiger 10.4.x:
http://www.apple.com/support/downloads/quicktime741fortiger.html
Pacifist:

I hope this helps! It's my first time doing this, too but as "canaries says:
"when downloaded drag the QT package over to the Pacifist window and when loaded select the 'Contents of Quick Time' line and then click the Install icon (top left). Should then all re-install everything from there."
If this helps, I will do a write up and post it on my blog and link it here.
Thanks everyone for the help!! 🙂
