Hello Chris,
I'm simply using the Windows Media Player 9 control, showing the media with
the 'play'-command and setting the property to fullscreen.
Is there a technique to overlay or blend-in something inside the video? Is
something like alpha-blending or color-keying supported?

Or is it impossible to achieve this by using the media player? If so, what
possibilties are there?

Many thanks in advance,

Roberto.
