SO like the title says, when I first start WMC in Live TV mode, the screen is black. Not the normal "No Signal" blue background screen. It is completely black. I can hear the sound just fine. Nothing will come up on the screen until I hit the reverse button and then go back to live. It only dos it when I first open WMC and start live TV. It doesn't do it when I change channels. Just wondering what is going on.
