Are you asking about how to programmatically control the Windows Media Player ActiveX control? If so, you might try posting your question to the Windows Media SDK newsgroup: http://www.microsoft.com/windows/windowsmedia/community/newsgroups/WindowsMedia/default.mspx?dg=microsoft.public.windowsmedia.sdk&lang=en&cr=US

If, however, you are writing your own app based on Media Foundation, the answer depends on the decoder that you are using. If you are using the WMV decoder, you can disable DXVA decoding by adding the following registry setting:

[HKEY_CURRENT_USER\Software\Microsoft\Scrunch\WMVideo]
"DXVA"=dword:00000000

Which decoder are you using? I may be able to help depending on the decoder.

Another option is to use a transform filter (from a DShow perspective) between the decoder and renderer. In your transform filter, accept only YV12 (or other sw mode GUIDs), and pass on media samples unmodified. I believe the same thing can be done for MFT tarnsforms.

Thanks,
