I have a cisco box with time warner cable in south east NC...I also run into the problem of losing tv picture, xbox does't give me the "we've lost your TV signal" message it just displays a black screen with no sound. I then have to turn my cable box off with the remote and then back on to get the TV to work. sometimes it will display the last TV show paused and will then zoom in and out but never start playing live TV. worked pretty good for the first week or so now it seems to be doing it more often. have not tried the hard reset (holding the on button for 10 sec.) would be nice if Microsoft could fix this.
