CLSID for DS filters needed to view Matroska files?
 

I need to know the CLSID numbers for the following DS files so I can write a bsfilters.dat file for a matroska (.mkv) file:

CoreAAC.ax
CoreVorbis.ax
Matroskasplitter.ax
Realmediasplitter.ax

Tried using Gspot, but it does not want to render the matroska file. If anyone knows the proper CLSID numbers, I would greatly appreciate it.

thanks.
