i've noticed the past few days when i am playing xbox 360 that my 612 goes on and off by itself (the lights on the receiver will come on for a few minutes and go back off a few minutes later). and now my recordings are broken up into sections, like a movie will be in 3 sections, 1 hour 5 minutes, 30 minutes, and 20 minutes. i have already unplugged from the wall for 30 seconds and plugged back in. my 722 does not do this.
