What’s more significantly new in this version:
* Support for H.264 video and HE-AAC audio codecs (new Aug. 21).
* Enhancements to full-screen mode to use hardware scaling for improved video performance and quality on systems running Windows 2000 and newer or Mac OS X 10.2 and newer.
* Faster rendering of vector graphics on multi-core CPUs.
* Higher quality and performance for downscaling large bitmaps (SWF 9 only).
Update: Choose the Intel Universal Binary, as the PPC version is for OS 9
