WME-9 is the new codec by Microsoft that is meant to be on par with MPEG-2 at much lower bitrates.(windows media 10 beta has the only decoder we know of)

At this time we are unable to broadcast a Transport Stream from the Tandberg VC-9 encoder. After encoding an SDI NTSC signal, the encoder outputs it in ASF format over ethernet as a Multicast Stream.

We are able to play the file using the microsoft NSC media file. This file can also be rendered in GraphEdit.

If we replace the Video Renderer with the AVI Mux/File Writer filter combo (and pick a *.avi file name in File Writer box), the AVI file is created (up to 3-5 hundred megabytes in about a minute).

The file is corrupt, however. It is not recognized as an AVI file. But, if I change the file extension to yuv and play that using the VQM software UYVY player, I can make out the picture but it is severaly distorted.

If I just play the GraphEdit graph without changing it, the Video Renderer does play the NSC file properly. What is going wrong with the conversion to AVI?
The out/in pin for the VC9 Decoder to Video Renderer reads RGB32.
