bdids just informed me that videolan works better for him for these videos than his normal media players, you can download it here:

i dont know what problem you are having in particular, but if you double click the real player window, or dont move your mouse for a few seoncds it should expand to full screen. if you move your mouse it shrinks it. annoying i know, but i dont think there is a way to fix it.
