SharpDX Not Implemented Exception

What could be the reason I am getting a SharpDX NotImplemented Exception?

SharpDX.SharpDXException: HRESULT: [0x80004001], Module: [General], ApiCode: [E_NOTIMPL/Not implemented], Message: Not implemented
at SharpDX.Result.CheckError()
at SharpDX.MediaFoundation.MediaFactory.Startup(Int32 version, Int32 dwFlags)
at SharpDX.MediaFoundation.MediaManager.Startup(Boolean useLightVersion)

this is on windows 8 desktop. the same code runs fine on windows 7.

Looking at native call for MFStartup

Seems it can happen when media components are not installed.

Here is a link with media feature pack download, hopefully should sort your problem (no idea why this is not here by default).
