Simple... vlc has this nasty bug (I'm guessing it's only with pulling from 
WME?) in which it apparently does not recognize the video bitrate, and so it 
streams it out at > 1500K. So even if the video being pulled is encoded at 
80K, and all I do is '#standard{access=mmsh,mux=asf,dst=:8010}' the video 
that gets streamed is > 1500K bitrate.

This has been reported for some time in the videolan forum but never got any 
attention I guess.

This is very possibly some sort of incompatibility with WME, all I know is 
that vlc will not obey the bitrate, whether it is transcoded or not...
