thanks for your offer, i am currently on a bussiness trip in the US and 
forwarding your email to the mailing list and the guys who are in charge 
of the filter. If you know how to use CVS ( WinCVS, TortoiseCVS ) you 
can obtain the latest sourcecode of our DShow parser from there and make 
some tests, however i recommend you join our IRC channel on 
irc.corecodec.dom #matroska and talk to the guys who are actually 
developing it ( Toff, myFUN, Blacksun, Cyrius ) about how you could help 
best ... i am sure you can help us, especially if you have a background 
in DirectShow already, and your help was very much appreciated.

I love the idea about a Vegas video plugin, didnt know their API/SDK was 
open for doing that, not to talk about Adobe Premiere and Ulead. If you 
dont feel like contributing to the DShow filter you could maybe still 
look into those plugins ? We certainly could help you with that, 
explaining to you how libmatroska would work, but after May 1st as until 
then we are all busy getting the release done smoothly.
