I would like to plug my Xbox 360 into the HDMI input of my Co-Star. I plan to use the Xbox as a Media Center Extender to my PC which has a USB tuner and is going to be my DVR. I tried a similar set up with my old Logitech Revue and found that it created significant input lag when playing games on the Xbox. I searched around for recommendations on how to alleviate the issue and the only answer I ever found was "Don't hook up your Xbox to a Revue." When searching for info on doing this with the Co-Star, I was unable to find any details. Has anyone tried this set up with the Co-Star? Does it have significant input lag or is it fairly usable?
