Update: When I changed my MPC settings to EVR, it resolved my issue. Not with WinTV though, which only seems able to use either VMR7 or 9. Also, when I change back to VMR Renderless, it gives me an error that it can't find the D3Dx9 dll. I remember getting the same error message while installing Hauppauge WinTV. Soooo, since my Nvidia 7300 card, is a DX9 card, the problem seems to be lie in the combination of my configuration, Windows 7, a DX9 card, Nvidia drivers.
