Fear not, Leopard users, Apple is still watching out for you. QuickTime 7.7 for Mac OS X 10.5 Leopard closes quite a number of security holes. As is common, we have no sense of how worrying these vulnerabilities really are, but it’s probably worth updating if you use QuickTime in Leopard. And if you’re running Snow Leopard or Lion, move along, there’s nothing to see here. (Free, 68.85 MB)
Set Per-Folder Views in the Finder
Tired of navigating to a particular folder and having to switch to List View every time? With Finder in Leopard, you can set viewing preference for each individual folder. Just navigate to it, and set the view the way you want (Column, List, Icon, or Cover Flow). Then choose View > Show View Options (Command-J) and in the window that appears, select the Always Open In... checkbox.

I downloaded from the link you provided. When trying to install, when I got to "Destination" a got a 'block' saying that I need to use the software update.
Okay, so I launched QT 7.6.6 hit the software update and it said I was up-to-date.
Okay, so I App Zapped it. Tried the QT 7.7 installer still at square one.
I keep playing around, but if anyone has any suggestions...mucho appreciato :)
using Mac OS X 10.6.8
http://www.apple.com/quicktime/download/ still downloads the old 7.6.9 dmg. File size matches my existing 7.6.9 file, so it's not just a graphics glitch.
Hopefully, Apple's on top of this.
Matt described it the best: "Apple, whose attitude towards backwards compatibility ranges from somewhat cavalier to downright heartless."
