Depending on the content of the Quicktime container, VideoLAN should
be able to accept the stream and transcode it to ASF over HTTP to your
server : http://www.videolan.org/streaming-features.html

Thank you for the tip. However I'm sill not getting this to work.
My video conferencing equipment is streaming out an rtcp protocol that is

OK well according to the features list, TCP over RTP isn't supported :
http://www.videolan.org/vlc/features.html

apparently only readable by Apple QuickTime even VLC isn't able to play the
video. Vlc only displays garbage when connected to the stream using the .sdp
URL.
Am I wrong in concluding that this can't be solved using Windows Media
Services?


Probably. WMS and WM in general is a proprietary ecosystem. Quicktime
uses *some* standard codecs (MPEG, H264 etc) and packetisation, but
not all

There are lot of approaches I've tried including: rdptoos, QuicTimePro, Vlc,
etc. but it always ends up in a dead end.
Is there any known transformation, codec or other between the two platforms?
Reason is that we prefer WMP as an end user player for fairly obvious user
support reasons.


Yeah I can figure that but I can't think of much to solve your
outstanding issue right now using just software. Without knowing
anything about the VC equipment, perhaps they've arranged it like this
to keep you "locked in" to their equipment.

The only other obvious solution is to capture the analog output - say,
use the VC equipments AV out ports (SCART, DVI, BNC etc) and use
something to convert it to a firewire stream, like the Canopus
TwinPact box : http://www.canopus.com/products/scanconversion.php

You could then encode the DV stream quite happily using an attached WM
encoder PC, and send it without further conversion to the WMS.
