Inability to play WMV format videos on DIP site

[Carriage5]

Hi John/Annabelle

O.K. This may be me being stupid.

I watch the videos on line in WMV format.Yesterday when I clicked the 'watch' tab it went to the page but the video was not there i.e. a demarcated square with the inside the same background as round the edges (white/grey light marble effect).
In the top left hand corner is a small black circle with a line through it.
It was working fine that morning and I checked other releases to make sure it wasn't isolated to that release.

As said above probably something I've done,though I can't think what.Any ideas?

Thanks
