FLVPlayBack Aspect Ratio

Question

Hi, I´m working with a FLVPlayBack object on Flash using AS 2.0... It load dinamicaly a lot of videos, in differents size. The problem is to make it show on all screen without mantain aspect ratio, I tried something like: Player._width=800; Player._height=600; and Player.setSize(800,600);

If I use Player.mantainAspectRatio=false, nothing show... Anyone have some idea, what i need to do?

Thanks Regards Rodrigo
