DynamicStream class play2 function and error overriding it

Question

Adobe made a "DynamicStream" class that looks pretty cool.  I'd like to use it.  The class contains the following code:
         override public function play2(param:NetStreamPlayOptions):void {
            throw new Error( "The play2() method has been disabled for this class.  Please create a separate NetStream object to use play2()." );
The compiler complains about this function.  Says "the method marked override must override another method".  It doesn't complain about it if I instantiate class in my main application file.  That's what the sample code in the Adobe productivity tools suite does - uses the class in the main application file.
If I use it in a custom component file though the compiler complains.
What do I do with this function if I intend to instantiate the DynamicStream class in a custom component file?

I too ran into this problem, if you are using the Flex SDK you must set the target flash player version to at least 10.0.0 otherwise the error occurs because play2() is not available in 9. By default the target version for all Flex 3.4 is 9.x, so you must change the target to 10. Let me know if you have anymore problems.
