Get ready for possible personal attacks, after all, you used the "POS" acronym. Someone will likely take it personally.
What do they say, the third HR20 is a charm? Just kidding. You know my feelings about this product launch. Seems to me that if they fixed the freezing/partial recording/missed recording bugs, they would have been prominently displayed in the release notes. I didn't see them.
Mine isn't locking up now, but I am going to reconnect my HDMI after this download, just for kicks. Component ended my lock-ups, it seems, but I know it's not a solution for others.
This morning I Googled the HR20 and visited several sites where people checked in with their impressions so far. All self-selected samples, of course. For every one good/great review, there are 5 negative ones. Sure, the downloads keeping coming, but the process just has a sort of surreal quality, as if D* isn't sure when they will get to the promised land, if at all. The one good thing to say is they keep trying. Not much solace to someone who is going on their 3rd or 4th box.
People who have long-term negative experiences with the R15 keep pointing to it as precedent. I never got one, but if HR20 subs/users are still suffering from the same major issues a year from now, it won't be pretty.
