Hi
I am developing a video transcoding app for a website.
It builds an encoding graph to convert files to AVI with the VP31 video
codec + WM Audio V2 for the sound.

One problem im facing on Pre DX9 systems is:
Asking the graph to add a source filter for WMV files, It puts in the
CLSID_NetShow {6B6D0800-9ADA-11d0-A520-00A0D10129C0} filter.
In graphedit, I can build the graph fine, but in my app, when that is
put in, instead of having 2 output pins, the filter shows 5 pins

Special pin
Stream 0
Stream 1
Stream 0
Stream 1

And all the pins fail to connect to the video compressor

I tried doing ICaptureGraphBuilder2::RenderStream, but that fails too.
I tried using the WM ASF reader but it shows 0 output pins
All this works perfectly on a system with DX 9 installed.

I'm at my wits end!

.
