I am not able to configure Xbox 360 with my computer. I have a Vista media center. I had see on web a video where you can stream your content directly from the computer to the media center with minimal configuration. The Xbox is not blocked by firewall. I had configured a separate port for the console. So it looks that there is no permission problem at all. I found a new problem here. The media center freezes when I try to access settings for Xbox. There is just a loading screen. My antivirus seems to working fine and it is not blocking the extender. Any idea behind this freezing issue.
