For all the valid points of not having users here do beta testing, or that it would be a limited improvement, none outweigh what some here would contribute overall. I get that some "bugs" might not hold up a release, or some might not even be considered a bug. But over the years how many times have we shook our heads wondering how a particular widespread problem didn't get weeded out that was found within hours of a release. (Sometimes minutes)
Scott did hit it on the head however, I can think of many times people reported a "bug" or problem that I never saw or in the end even though some had it, the vast majority did not. Right now the artifacts on what seems to be for a few channels seems to be showing for a handful of people on the boards on the same receivers I have, I see no problem.
But with all that said, JSheridan is correct, where are there better beta testers than here?
