Turns out I can't get to the silverlightControlHost div. Everytime I try to get the contentWindow or contentDocument of the iframe I create I get an "Access is denied" error. I would imagine that's because I'm going to a different domain.

It appears to be inside of a div. My DOM Tree is as follows (the relevant parts anyways):
<html>
<head>...</head>
<body>
<div id="mainContentBorder>
<div id="mainContent"> 
<iframe> 
<html>
<head>...</head>
<body>
<form>
<div id="silverlightControlHost">
<object>...</object>
<iframe>...</iframe>
</div>
</form>
</body>
</html>
</iframe>
</div>
</div>
</body>
</html>

Using GraphEdit I found out that the AVI file that I was using had a format that was unsupported by the machine. I did some conversions, and it now runs on the test machine as well!

Thank you very much Maxim Kartavenkov! You will be listed in our games credits for your help. I'll be sure to send you a link to our game once we finish it next month.

Holy crap! I did not know this thing existed! I will definitely try running this tool tomorrow and see what's up.

Unfortunately, it still does not work on the test machine. For now I'm going to just use AVIFile to get videos to work.

Here is my new code for InitializeDevice if you or anyone else would like to take a look at it:

HRESULT VideoAllocator::InitializeDevice (DWORD_PTR dwUserID, VMR9AllocationInfo* lpAllocInfo, DWORD* lpNumBuffers)
{
EnterCriticalSection(&m_CriticalSection);

if (lpAllocInfo == NULL)
{
#ifndef _RELEASEBUILD
printf("Invalid Allocation pointer in InitializeDevice().\n");
#endif
LeaveCriticalSection(&m_CriticalSection);
return E_POINTER;
}

if (lpNumBuffers == NULL)
{
#ifndef _RELEASEBUILD
printf("Invalid Number of Buffers pointer in InitializeDevice().\n");
#endif
LeaveCriticalSection(&m_CriticalSection);
return E_POINTER;
}

D3DCAPS9 d3dcaps;
DWORD dwWidth = 1;
DWORD dwHeight = 1;

m_pDevice->GetDeviceCaps(&d3dcaps);
if (d3dcaps.TextureCaps & D3DPTEXTURECAPS_POW2)
{
while (dwWidth < lpAllocInfo->dwWidth)
dwWidth <<= 1;
while (dwHeight < lpAllocInfo->dwHeight)
dwHeight <<= 1;
lpAllocInfo->dwWidth = dwWidth;
lpAllocInfo->dwHeight = dwHeight;
}

// Try creating textures first, if the machine can handle it.
lpAllocInfo->dwFlags |= VMR9AllocFlag_TextureSurface;

ReleaseSurfaces();
m_dwSurfaces = *lpNumBuffers;
m_pSurfaces = new IDirect3DSurface9* [m_dwSurfaces];
HRESULT hr = m_pNotify->AllocateSurfaceHelper(lpAllocInfo, lpNumBuffers, m_pSurfaces);

// If we failed, and the format is not an alpha format, then we need to render
// to an off-screen surface, and copy decode the images onto a private texture.
if (FAILED(hr) && !(lpAllocInfo->dwFlags & VMR9AllocFlag_3DRenderTarget))
{
// Is the surface a YUV?
if (lpAllocInfo->Format > '0000')
{
D3DDISPLAYMODE dm;
hr = m_pDevice->GetDisplayMode(NULL, &dm);
if (FAILED(hr))
{
#ifndef _RELEASEBUILD
printf("Failed to get the Display Mode in InitializeDevice().\n");
#endif
LeaveCriticalSection(&m_CriticalSection);
return hr;
}

hr = m_pDevice->CreateTexture(lpAllocInfo->dwWidth, lpAllocInfo->dwHeight,
1, D3DUSAGE_RENDERTARGET, dm.Format, D3DPOOL_DEFAULT, &m_pPrivateTexture, NULL);
if (FAILED(hr))
{
#ifndef _RELEASEBUILD
printf("Failed to create a private texture in InitializeDevice().\n");
#endif
LeaveCriticalSection(&m_CriticalSection);
return hr;
}
}

lpAllocInfo->dwFlags &= ~VMR9AllocFlag_TextureSurface;
lpAllocInfo->dwFlags |= VMR9AllocFlag_OffscreenSurface;

hr = m_pNotify->AllocateSurfaceHelper(lpAllocInfo, lpNumBuffers, m_pSurfaces);
if (FAILED(hr))
{
#ifndef _RELEASEBUILD
printf("Failed to work around this machine, VMR-9 ain't gonna happen.\n");
#endif
LeaveCriticalSection(&m_CriticalSection);
return hr;
}
}

LeaveCriticalSection(&m_CriticalSection);
return hr;
}

Thank you very much for taking a look at this. I have implemented the solution on my machine (the Windows 7 one), and it works. Unfortunately, I have to wait until Monday before I can test to see if this works on the target machine (the Windows XP one).

I will inform you of the results, and if it works, I will be hitting that green button above, and a very big special thanks in the game's credits!
