When Leopard was release it was packaged with a new version of Apple's QuickTime Player. 7.2.1 however is not publicly available for download on Apples Website, leading us to believe that its release, or a higher version is coming around the corner.

Currently Apple's provides QuickTime 7.2, which was specifically built for "Mac OS X v10.3.9 and v10.4.9 or later". Recently we were encountering several issues with a 7.2.1 and iTunes installed on a HTPC. Suspecting a bad QT installation we went to download the latest available to discover it could not be installed on Leopard.

Currently there are now major differences between the two versions that are jumping out at us. There is the obvious user interface changes such the border-less player windows, pro logo change, and leopard compatibility, but the rest of the application seems the same, all the way down to the preferences.
