ActionScript 3.0 :: Use The FLVPlayback Class With Flashdevelop?

I'm trying to use the FLVPlayback class with Flashdevelop(ie - I am not using Flash CS3 and I don't have the privilege of dragging an FLVPlayback onto the stage). In the as3 language reference it says:

To access the properties, methods, and events of the FLVPlayback class, you must import the class to your application either by dragging the FLVPlayback component to the Stage in your Flash application, or by explicitly importing it in ActionScript using the import statement.

From the above it makes it sound like you can use FLVPlayback without having it in your Flash CS3 library...but I've done some reading and everyone is saying that it must be in your Flash CS3 library to use.

When I try and do this in Flashdevelop(simplified code):

Code:
import fl.video.FLVPlayback;
var video:FLVPlayback;

I get:

Type was not found or was not a compile-time constant: FLVPlayback

I have 3 questions:

1. Is it possible to use FLVPlayback with pure actionscript? ie - can I just import the class with the import statement and use it without having to connect it in with some IDE like flash or flex?

2. fl.video.FLVPlayback is listed in the AS3 language reference...even if FLVPlayback isn't going to work without it being in my library - why do I get an error when I try to import fl.video.FLVPlayback? Why can't this class be found?

3. If I can only use FLVPlayback by adding it to the library, then are there any video player classes out there that are pure actionscript without this limitation?
