I recently upgraded to a 922 from a 622. I have S1.18, running in Solo mode, and I run an HDMI splitter to 2 HDTVs. The receiver is not in an enclosed space, and I also have a USB hard drive attached to it. Almost every morning, about 15 minutes after I turn on the receiver it locks up (screen frozen, no sound). If I change the channel it un-freezes, and its usually OK for the rest of the day. I did a search, but I didnt see anyone else with this specific problem. Could it be my HDMI splitter? I never had a problem using the splitter with my 622.
