Not sure if you had a question there!
There is something that appears to be misleading in what is said about the new version. Director has always been able to do full screen video, you make a full screen projector, have its stage be the size of the monitor (or use a movie in a window), and set the video sprite to fill the stage.
Many people will think that shockwave can now go full screen in a browser, like Flash and Unity can, but I don't think that is the case.
The other aspect of the new features is that Director does now have the ability to play some video formats without needing QuickTime to be installed.
i think its more of a support for High Definition videos 1080 and alpha channel in flv's.
