I was just on the phone with a tier 2 tech support person discussing a problem that I am having with my HR20. My HDMI output was working fine and suddenly the sound went out. I have a couple of things to try. New cable etc. But the interesting thing is, that he told me to wait until tomorrow before I replace the cable and try it again. There is supposedly another update being released at 2 AM. tonight. Just thought I would pass this along. I hope he is telling me the truth.
