I'm not getting any errors on either 8 or 9 on any page.
Can you post your OS, browser, and version of Silverlight as well as the full error text and symptoms you are getting?
I haven't tried other OS's but I am able to play videos just fine on Windows in either Firefox or IE. Silverlight is currently only supported under XP, 2k3, Vista, and Mac OS 10.4.8+ (intel or PPC). Only Firefox and IE are supported on Windows, Firefox and
Safari on Mac.
Okay, try the following things to see if you can get it to work.
1) Hover over the preview image. Do you get a "finger" cursor and see an outline appear around the image? Click the image to activate the WMP ActiveX control and you should be able to play just fine. (I often see this problem and just did on this video).
2) If that doesn't work, click the "Full Screen" button. This will launch the same streaming URL into WMP. Did that work? If not, there's a streaming server issue we can look into.
Let me know if that fixes your problem. Insert mandatory "v4 will fix it" statement here.
