When you first click a video on our web site, it might ask you to download Silverlight.
This is a new Microsoft product that is effectively the next generation of internet media player, delivering a smoother and higher quality experience than previous efforts.
It is available for PC and Mac.
Silverlight is relatively new but you will find it becoming increasingly common over the next year or so.
We’ve tested it extensively and have found it to be quick and trouble-free.
You can find out more at the Silverlight web site.
