WMP library and MKV files

[Eles10]

Its sad that in windows media player MKV files are placed in the "Other media" section instead of "Video" section. Only AVIs and WMVs go in the "Video". But I would like to have all those files in Video category :) What am I supposed to do?
I realized that creating a new string mkv=video in the key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer \MLS\Extensions) forces WMP to place MKV files in "Video". BUT then, when I run them through clicking from the library, I cant use the seek button.
Every click on the seek line leads to the new start from the beginning. In the other way, when I just play the file from explorer, WMP starts and everything works correctly.
Can anyone help me with this?

Windows Vista 32bit, WMP 11, ffdshow rev.1322, Haali media splitter 1.7.189.11, VSFliter 2.33

That's a DirectShow filter problem. Either change the filter you're using or get the developer to fix the issue on their end. The same thing happens to FLAC files in WMP because the DS filters are poorly written.

Thanks, and what should I do? Could you tell me in a more specific way? By changing the directshow filter you mean different splitter or decoder or directx or what? I m not familiar with this. Actually I have tried everything possible and no success...
