MMS stream splitting is not supported in ISA Server 2004

In Microsoft Internet Security and Acceleration (ISA) Server 2004, live stream splitting to split multiple Windows Media Technologies (WMT) streams is not supported.

In ISA Server 2004, Microsoft Media Server (MMS) stream splitting is no longer supported for streaming media. This behavior is different from Microsoft ISA Server 2000. In ISA Server 2000 you can configure live stream splitting to split multiple WMT streams using a WMT Server that listens on MMS port 1755. This feature is only supported in Microsoft Windows 2000.
