This, by it self does nothing, per se. First you need
AME. Then to expand what AME can do (which is how it was designed) you need these media definitions.
But AME is not an uploader, it's an embeder. So if you've uploaded .MOV files to your server, you can use the QuickTime definitions
in my other thread (I'll be adding one to this thread sometime this week) to embed them in posts.
