As you have undoubtedly noticed, the Silverlight Streaming service has not yet been upgraded to work with Silverlight 2 RTW. This will be done shortly. Until this work is completed, here is a short FAQ about the side effects:

• Silverlight Streaming will work with Silverlight 1 and Silverlight 2 Beta 2 only
• The Silverlight Streaming upload stack relies on a Silverlight control, so the Browse button will be disabled if you have Silverlight 2 RTW onlyour machine
• This will be true for both the Manage Applications and Manage Videos scenarios

We apologize for the inconvenience caused by this delay, and are working to perform the upgrade as soon as possible.
