In addition to my 722K, I have an Xbox 360 at each TV, that I use for gaming and as a Media Center Extender for my music, pictures and encoded video. Over time, I have used the Xbox more and more, as I have ripped and encoded more of my DVD library. I had gotten quite tired of getting the Xbox controller everytime I wanted to watch TV on it, so I got to googling and found an answer. I just wanted to share it, in case any of you guys do the same thing. On the 722K remote, hold DVD until the lights flash and the remote is ready for programming... Enter 792# for the code. Now, your 722K remote will control the Xbox, as well as the Media Center portion. Hope it helps someone.
