This has to be an AppleTV bug somewhere with the HDMI
I've tried this with HDMI connected directly to a Sony TV, and through a Yamaha receiver, and I see the same results with either device. I will concede that not all devices conform to standards 100%, but if my HDMI cable box and TiVo can all work without crashing routinely, I don't see why my AppleTV can't as well.
I have seen both the Apple Logo bug (usually the Apple TV will reboot itself after a few minutes, but not always), and I've also seen a blank black screen - changing the input on my receiver over to something else (cable box or DVD player) and back over to the AppleTV will reset the black screen bug.
This did happen a lot more often pre-2.0 (it would require me to pull the plug every time back then), so it has got better with the new 2.0 software, but it still exists. I don't see it once a day any longer, the black screen I see once a week or so, and the Apple Logo reset maybe every other week. It's still annoying.
