ok, we talked with the dev team, and they think this might be a proxy issue.  Sampy made a couple of posts on Channel9 about this that he thought might help you out.  They can be found here:

Nothing out of the ordinary Adam; I load the page from the link in the RSS feed and then click the Play button on the player. I get a quick jump of the progress indicator [around 2 cm of travel) but no video feed. The other functions [outside of the transport controls] behave as expected. As I said: this is all video on Edge not just the WDS video [which I very much want to view given the deployment I'm facing].

I removed and reinstalled Silverlight from Add/Remove them installed from EXE source. Tried agian but no S.O.A.P

Thx for the reply.

Any idea why posted videos refuse to play from this site (that's all videos that I've tried [>8])? Silverlight installed... <check> update to SL... <check> every video on this site doesn't play... <check>.

Help a brother out...
