I have a Harmon Kardon AVR 325....2 problems. 1. While watching dvd's/cable/HD/SAt....it randomly goes off....this can happen every 5 minutes or every hours. Its so annoying. Anyone know whats going on? 2. I cannot watch HD with my "rogers HD terminal" because there is no sound......normal cable channels have sound...but not HD (sometimes i have to change the channels to get sound mind you.....even with normal cable). When i put it on HD....the speaker lights on the Harmon just flash...like its trying to connect...but nothing happens. could it be my rogers box has issues or is it completely the HK receiver? Thanks so much.
