MKV and OGM playback semi-solved
 

I am able to play ogm, matroska and avi no problem. I installed the following:

VSFilter / DirectVobSub v2.37 http://www.inmatrix.com/zplayer/formats/vsfilter.shtml ... installs vsfilter.dll
Gabest Matroska http://www.inmatrix.com/zplayer/formats/matroska.shtml .... installs MatroskaSplitter.ax
Koepi's XviD http://www.koepi.org/xvid.shtml
DivX http://www.divx.com/
ffdshow 20041012-sse http://sourceforge.net/project/showf...group_id=53761 (I don't think you need it but just in case.)

I am using BSplayer Pro version 2.11 Build 940

So, what still is your problem,if it's only semi-solved??

Normally if you install DivX and XviD you won't need ffdshow. And if you install ffdshow, won't need DivX and XviD. Maybe you will consider to install a newer build of ffdshow, that one is 2 years old :D
