HDMI and Windows Media Center don't always play nice with each other. This is even more evident when hooking up your setup through an A/V Receiver. There are two general problems that occur when you turn on your TV. First, sometimes the HDMI sync/handshake will change your resolution from 1080p to something less desirable. Second, sometimes you will get the dreaded "Display Driver Error" when trying to play TV. Both of these problems can be solved by minimizing and maximizing Windows Media Center to force a HDMI Resync. This little app, automates that for you so you don't need to leave your couch.
