SWL Many thanks for the extra data point, Stephen. With this new info, I think that perhaps the problem is one of those barely-within-margins sort of thing, perhaps associated with PSIP as implemented in the Accurian. The fact that the STB might be more susceptible when warm does not necessarily mean that it's getting overheated. In fact, my Accurian runs nice and cool, even after being on for some time. Here are some facts that occurred after that post, to support this theory. I tried the next day, right after arriving at home, and the (stone cold) Accurian box was still having this problem with 4-2. And the cure was the same: power down, then power up while pressing the channel up or down button, until the system starts receiving a station again, to knock it off 4-2. I also found that you canscroll right on past 4-2 with no problem. It's just allowing 4-2 to sync up that then creates this freeze. Then I went upstairs and tried the Digital Stream 3150 Plus, a newer variant of the same design, and it seemed to be fine. Also, the Accurian was fine with respect to 4-2 before. I'm sure I scrolled through 4-2 many times, with no problem. That's what makes me think maybe something right on the hairy edge. Also, in private e-mail yesterday, I was informed that and older Samsung box exhibited exactly the same symptom. The problem, in their case, was traced to a PSIP parameter not being updated quite as frequently as the Samsung box expected. Samsung provided a patch which solved the problem. I suppose that patch made the PSIP code in the Samsung more tolerant of PSIP parameter updates being out of spec. Possibly the same issue here.
