ITunes 11.3 Update

Apple released ITunes version 11.3 today. After the update is installed, the itunes Extras feature will be available for high-definition movies purchased from the itunes Store and stored on a Mac. In addition, users of Apple TV (which needs to be upgraded to 6.2) can also enjoy this feature. As for the IPhone and IPad users, they need to wait until this fall for IOS 8.

The ITunes Extras can add a more interactive experience to some video content in the form of behind-the-scenes video, image sets, cast reviews, cast interviews, exclusive clips, short films, etc. But that's not mandatory--the cast can choose to use ITunes Extras or not. If the cast wants to try, Apple has provided the template.

Also, the HD movie that you purchased before will automatically and freely add iTunes Extras content.
