I know for some of the other multimedia codecs there is a true breakout of the data that is sent down the MMR virtual channel to the endpoint where it then uses the client-side CPU to process and display the multimedia. I will double check on the Flash virtual channel though as this is the first I had heard of it...and my sources are usually pretty good! :-) That said, all the MMR stuff is still within a RDP virtual channel so from a network perspective you would only see RDP traffic. The USB redirection is truly a complete breakout of the USB traffic from RDP into its own unique TCP stream on port 32111.

Seperating it out of the main stream and into it's own channel.<br><br>Carlo. Interesting, I believe they are also doing this with the new FLASH throttling improvements.
