ActionScript 3.0 :: Resize Flash Overlay Plugin To Fullscreen In Video Player?

It's with a Flash overlay that has been custom made to overlap a .flv video running in Flowplayer (open source video player at flowplayer.org) The Flash overlay is mostly transparent and just includes a few buttons over top the video to allow visitors to share, email and visit a related website. Take a look here for example:[URL]

The video and Flash buttons work fine when videos are played within Flowplayer at normal size in the browser, but when making it fullscreen using Flowplayer, the Flash overlay plugin does not resize to fullscreen with it. Then, when made regular size again it gets distorted, as you can see from the example.

I know it might involve creating a custom onResize() function, but I haven't figured this out yet with Flowplayer. There are vague instructions & snippets of code here under "Layout management" section on flowplayer . org/documentation/developer/writing-flash-plugins.html

Code:
override public function onResize():void {
/*
set _childButton width according to my new width,

[Code]....

Interesting, but doesn't tell me much of what to do. I have a feeling it might involve making a new .as class in Flash and associating it to the custom buttons overlay .swf. On the right track?

get the overlay to resize using onResize and what code should be used would be very helpful. Others may be also trying to make custom overlay plugins too, and the fullscreen issue would be the next step to know after that and make it look more complete.
