Mencoder codec - wmavds32.ax

I am setting up mencoder on CentOS and I have the following error:

[flv @ 0x86751c8]Unsupported video codec (7) IMediaObject ERROR: 0x8724f4c input format not accepted (0x80040205 : -2147220987) Win32 LoadLibrary failed to load: wmavds32.ax, /usr/local/lib/codecs/wmavds32.ax, /usr/lib/win32/wmavds32.ax, /usr/local/lib/win32/wmavds32.ax Warning: DS_Filter() could not open DirectShow DLL. (DLL=wmavds32.ax)

I am going through codecs on http://www3.mplayerhq.hu/MPlayer/releases/codecs/ and none seem to contain wmavds32.ax

Any ideas how to fix this?

Thanks!

Codecs are available on http://www.mplayerhq.hu/design7/dload.html underneath the Binary Codec Packages section. It contains wmavds32.ax per http://www.mplayerhq.hu/DOCS/codecs-status.html
