I, along with numerous other users out there, have complained about the lack of full-screen support in QuickTime player for years now. Especially since iTunes was updated for video support awhile back and you could watch videos in full-screen from iTunes, but not within QuickTime. You had to pay the fee for a QuickTime Pro Key.

Today, that has changed.

Apple previewed Leopard at WWDC 2007 and one of the technologies called QuickLook, makes heavy use of full-screen video support directly from within the Finder. After the WWDC keynote, speculation that Leopard would provide full-screen support without the need to purchase a QuickTime Pro Key arose. With QuickTime 7.2 released today for Tiger, you can finally watch all videos full-screen without the need for a Pro Key.

QuickTime 7.2 addresses critical security issues and delivers:
- Support for full screen viewing in QuickTime Player
- Updates to the H.264 codec
- Numerous bug fixes

QuickTime 7.2 is a free update.  Check Software Update.
