Adverts will fill the bus screen with no black border,
the black border is shown here because your computer
monitor has a higher resolution than the bus screens.

This advert may play back slowly on older compuers,
since it involves drawing a lot of complex moving graphics.
The version shown on the buses will be completely smooth,
but you will need to install the free DIVX player software
before you can see it.

You can get the free DIVX player here
and the divx version of the commerical from here
