Fixes and Features in Adobe® Flash® Player 9 Update 3, Version 9.0.115.0 Flash Player 9 Update 3 extends the performance and standards compliance advances introduced in Flash Player 9. Of key importance, this update adds H.264 video and High Efficiency AAC (HE-AAC) audio codec support that opens up a broad ecosystem and selection of standards-based video — up to HD quality — that developers can leverage in their applications. The update also features hardware accelerated, multi-core enhanced, full-screen video playback for high-resolution viewing across major operating systems and browsers. Adobe Flash Player 9.0.115.0 includes security enhancements described in. A summary of the new features that developers should be aware of includes:New audio/video options • H.264/HE-AAC codec support Flash Player 9 Update 3 includes H.264 video and High Efficiency AAC (HE-AAC) audio codec support that opens up a broad ecosystem and selection of standards-based video — up to HD quality — that developers can leverage in their applications. Supporting a subset of MPEG-4 Part 12 (container) and Part 10 (H.264), including baseline, main and high profiles, Flash Player can play back existing MP4, M4A, MOV, MP4V, 3GP and 3G2 content. Improved Performance • Multi-core support Speed the rendering of vectors, bitmaps, filters and video, including true 1080p video, with new multi-core support that takes advantage of up to 4 CPUs.

• Hardware scaling Improve the performance and quality of full-screen video through the use of hardware scaling. • Multi-threaded video decoding The VP6 video codec now runs in a separate thread on multi-core systems, enabling true 1080p video. In addition, the responsiveness and decode blockiness of the VP6 codec is improved with this change.

• Image scaling A new algorithm for scaling bitmap images enhances the quality and rendering performance of downscaled images. • Flash Player cache The Flash Player cache enables common components, such as the Flex Framework, to be cached locally and then used by any SWF from any domain. Use of the Flash Player cache can significantly reduce SWF file sizes and speed application download times. • Flash Media Server buffering The stream buffer is maintained while a stream is paused. Universal Reach • Full screen mode for Linux Full screen mode with hardware scaling is now supported in Linux. • Accessibility support for the plugin Flash Player 9 update 3 adds support for Microsoft’s Active Accessibility (MSAA) API to the plugin, enabling consistent support across plugin-based and Internet Explorer browsers. • Mac Os X Leopard support Flash Player 9 update 3 now supports the Mac OS X Leopard operating system.

However, you may have run into a problem trying to use your Western Digital hard drive with multiple operating systems. This is because you must format the drive with a specific file system before using it with a computer, and Windows and Mac computers run on different file systems.
