Did anybody point you to CoreVorbis already ? 
http://corevorbis.corecodec.org . I also wonder why you didnt modify 
Tobias Waldvogel's existing, and well working, filters, but decided to 
rewrite them completely, and even using an inderior approach by 
including the source filter into the decoder filter ( which is clearly 
against the standard DirectShow approach BTW ) ?

We could have used your Speex decoder filter to play Speex from matroska 
container, but right now its unusable for us as it is.

No offense, i just will never understand why developers tend to rewrite 
stuff completely, instead of taking other people's existing code ....
