Roku has responded to my email to customer support. I actually missed the first one as I thought it was just another email about a message posted here by a Roku robot. I have done the reset that they requested and provided the info that I provided previously here. They seem to think this is a Roku TV problem. Maybe that support email address is for Roku TV. Regardless, I seem to actually have a warm body that is looking into the problem.
I told him about this Community thread and the number of people with the same problem and the dissatisfaction being voiced. Told him to check this site for further info. It also turns out that there is a similar thread with only 6 pages so far about the same problem. Somehow, I managed to post to both, so now I get emails from both. I'm going to try and send links to these threads to the Roku rep..
I'll provide updates as things progress. I actually have a ticket number.
