The video unit still doesn't allow you direct access to the screen, it 
only has a virtual buffer (a simple array) to which you can write and 
afterwards you can tell the video unit to blit its contents to screen 
(with a choice whether only the changed parts should be updated or the 
whole screen).

Direct (text video) memory access is simply not possible under Win32.
