Yes, the last two weeks worth were customer candidates. I've only been playing with the CE for a year, but I havent seen more than 3 customer candidates before it turns into an NR.
What I did notice in this weeks release notes was that last week said "customer candidate" in the risk section, but this week it says "moderate risk" instead. So maybe they realized they were further than 3 weeks away.
I've also noted that the directv firmware in general seems to have to deal with a lot of tolerance variances in the hardware, and that some tweaks work well for 98% of people and badly for the other 2%. The system test that tosses out the bad dish aiming for some people is one example. The wild variance in remote response times is another. That some people never had problems with MRV while others had plenty is a third. There also seems to be some variance between models and within the same model. I've noticed on my advanced test menu that there are a number of things in the box with version numbers, so maybe the in-model variances are due to other internal parts/versions being different even though both are HR20-100's.
I would imagine at some point when they get the stuff working for the vast majority of customers and cant accommodate a minority of boxes/configurations that are still tossing their cookies, they roll it out anyhow and let the small number of customers it affects to call up and swap out their boxes.
Hopefully they have the protection plan...
