I've found that after calling this function my game will no longer minimize when alt-tab is pressed. This is on both ATI and Nvidia cards under XP. On Vista alt-tab still works after calling the function. Note that you'll need a reasonably recent platform SDK to get this to compile. It probably won't return true or cause problems unless you have media player 10 or newer installed too. Any suggestions on how to make alt-tab work again after calling this code would be appreciated.
#include <vmr9.h>
#include <d3d9.h>
#include <atlbase.h>
#include <comutil.h>
#include <dshow.h>

bool BreakAltTab(void)
{
    IBaseFilter* pBF = NULL;
    HRESULT hr = CoCreateInstance(CLSID_VideoMixingRenderer9, NULL,
                          CLSCTX_INPROC,
                          IID_IBaseFilter,
                          (LPVOID *)&pBF);
    if(SUCCEEDED(hr))
    {
        pBF->Release();
        return true;
    }
    else
    {
        return false;
    }
}
