Video is scaling down not up in fullscreen

Hi Im working on a presentation, created as a projector. It can run both in a window or in fullscreen. In the presentation I have videos playing filling the screens width. They are encoded in f4v format.

My problem is that when I switch to fullscreen the video scales down not up!! It becomes prop around 320x180, not a scales up 1280x720…

Very strange behaviour. Anyone knows anything about this problem?

Some more info: The fullscreen is not the fullscreen command of FLVPlayer, but of the stage. Also Im am doing this completely in code.

I have set myVideo.fullScreenTakeOver = false; as I need the endframe of the video to match a still image.

Thanks
