Hello, Twice in the past couple of days, I've had an abnormal issue with my HK525. While watching TV in Logic 7, all rear speakers were suddenly engaged, causing an echo effect throughout the room. This continued until I turned the 525 off and back on again. Stopping & restarting the media did nothing to help. The first time this happened we were watching a tape (not my fault, some friends brought it over, I would have picked the DVD). Second time I was watching DirecTV. Has anyone else experienced this? Right now, it is only a mild annoyance, but if it continues to happen I'm going to be a little upset. I am hoping this is not a problem with my particular receiver. I've owned it a little over a month and other than this, it has performed flawlessly. The only thing that has recently changed on the unit is the addition of a Gamecube into the video3 inputs. Gamecube was powered off during both of these episodes. Thank you in advance for any assistance.
