racingpost drm problems with media centre

i have just become a member on the racing post site thinking it would be great to be able to view past replays of races. My computer was broke a couple of weeks back and i now have windows 7 on there, well after speaking with racing post customer services it seems you can view 2009 replays ok but 2008 and earlier uses windows media player DRM instead of the now used flash player for 2009 onwards. I have tried everything but cant find how to get the right DRM set up for this windows 7. Any help would be greatly appreciated.
