Oct 23 release. Works in Mavericks.

No more incompatible software on my system.

I notice that the QuickTime components are still 3.2.016 but if you install this download and try to run the app or a .wmv file, it asks if you want to update the player to 3.2.1 - clicking yes takes you there.

Way cool.
