I cannot get xfinity to work properly on my xbox. when i manually entered the code from the bottom of my cable box (pr150) code, when i try to watch it freezes constantly with no audio. When i use the xfinity x1 code it would work but would not display in hd. I really am have a hell of a time figuring out what i am doing wrong. When i try to let the automatic method pick up the service on its own, it doesn't work at all.
