Hi Ant, I can't guess exactly what you've done wrong, but when doing this type of HUD style work it's important to make sure that the Camera's view and projection matrices are set appriately as well as any transforms in the scene graph so that the geometry coords you set up in end up in the correct positions.
The osghud and osgmovie examples are probably good places to start when looking how to do this. Robert.
