While I can not help you with MCE/Vista... Have you tried hooking up with VLC? Try to isolate the issue between the HDHomerun and the PC. I use mine with SageTV, which works fine, but I had to learn the lesson that for SageTV, I had to have the HDHomerun applet running as well. I assume you have also posted your problem on the SiliconDust forum.
