I downloaded the December 2005 update, and when I put in BC games, it would seize up the system. Just a black screen would be there, and I'd have to restart the system. I burned the update on a cd and loaded it a couple of times... to get it to work... but now when I put in BC games it reads them like a dvd player would. A neat animation screen with the XBOX logo shows up, and the screen says "This is an Xbox game disc. Please put it in your Xbox to start playing." I have since been soley playing Xbox360 games, but want some of my XBOX games on there... any ideas what this could be or suggestions on how to fix it?
