This is mighty strange... I wonder if there's something wrong with DirectShow on your machine somehow. Try re-installing the DirectX End-user runtime and update your video card drivers. After this, you may want to reinstall the dwrap 1.0.1 test9 dlls (earlier on this thread) to get back to the VMR renderer, and disconnect your other audio / video device, just in case. Then try running the game again. On my side, i'll try to come up with a small DirectShow filter hack that will let us determine if video data is actually reaching the video renderer filter. After we know for sure either way, there's a couple more possibilities we can explore. I'll try to post a new version soon.
