Mplayer is using the hardware video overlay feature of your video
card, which bypasses the framebuffer. Try using mplayer with the "-vo
x11" flag (or another video out driver, check "-vo help").
With the x11 driver, scaling has to be done in software, so that will
be a lot slower, but you can make screenshots this way.
