I added some LGPL code to decode RV40, yes. But it's using DirectShow to 
access the original Real DLLs. So I didn't even think about submitting 
it here.

DivX, Inc. is not called DivXNetworks anymore :) And they are already 
sponsoring their own employees to improve FFMPEG ;) Plus RealVideo 
decoding is not really a priority for us. But that makes DrDivX one of 
the very few tools that can convert many matroska files (RV9) to 
something more usable.
