Answer : How to block video and audio streaming  in ISA 2006

         I have a rule with theses protocols being denied, MMS,MMS SERVER<  RTSP< RTSP SERVER.

Why?  That is a waste of time.  Everything is denied by default,...so don't allow them to start with and they won't be allowed.

My problem is that I  have some streaming sites still making it through

Then they probably are not using one of those protocols.  Most are not.  Most use HTTP to stream.   You can't block that very easy without blocking the whole site.
