Flash :: FLVPlayback Video Smoothing

Earlier this week I posted an entry about activating smoothing for plain Video objects in Flash 6 or later, and stated that there was no way to apply this to the newer video playback components. Well, I was wrong.
Andrew Wason from Motionbox Inc. sent me the following workaround, which allows you to activate video smoothing for FLVPlayback components
(in this case the instance FLVPlayer):
MovieClip(FLVPlayer.getVideoPlayer(FLVPlayer.activeVideoPlayerIndex))._video.smoothing = true;
By converting the component video player’s data type to a MovieClip, you get around the video player’s access control and can directly access its video object. This way you can then change its smoothing parameter
