Thanks for your help Remy, I got it working using a sample I found in the 
November 2001 MSDN, and adding the registry key that we talked about 
earlier.

As for adding to the ROT...

namespace
{
DWORD rotReg = 0xf000000;
}

DWORD DirectXUtils::AddGraphToROT(IUnknown* inGraph)
{
   CComPtr<IMoniker> moniker;
   CComPtr<IRunningObjectTable> rot;
   DWORD retVal = 0;
   if (SUCCEEDED(GetRunningObjectTable(0, &rot)))
   {
      WCHAR wsz[256];
      wsprintfW(wsz, L"AutoPlayInterceptor %08x  pid %08x", 0,
                GetCurrentProcessId());
      if (SUCCEEDED(CreateItemMoniker(L"!", wsz, &moniker)))
      {
         retVal = rotReg;
         rot->Register(0, inGraph, moniker, &retVal);
         rotReg = retVal ? rotReg + 1 : rotReg;
      }
   }
   return retVal;
}

was what I had previously, which was adding to the ROT, I am now using 
the code from the MSDN article...
