Got network craptures?
Got the Supportability update?  It includes lots of fixes (kind of a 
mini-service pack)

Subject: [isapros] Silverlight through ISA 2006

Hi,

I can't see the video in the URL
http://www.microsoft.com/emea/spotlight/Steve_Riley_The_Fortified_Data_Cente
r_in_Your_Future.aspx through ISA 2006 SE when IE7 is configured as a Web
proxy client. It gives always the following "Silverlight eror message":
  ErrorCode: 4001
  ErrorType: MediaError
  Message: AG_E_NETWORK_ERROR

The ISA Server and the XP client are fully patched. When I disable the Web
Proxy settings in IE7, it works flawless!

In the ISA log I see the following failing entry:
