So, there's really something odd going on here. I've been trying to update my ATV3 to the latest ATV software and every single time it says it wasn't successful. I've unplugged it, restarted it, etc many times but still nada. What gives? Also, when I "restart" by pulling the rear power cord then back in, there are times when I get no picture. I'm assuming that no signal is being sent through the HDMI or it's not starting up? But, I usually have to do this several times until it finally works. I only do this "restart" when I experience issues that I think a restart would fix. Other than that, everything else works. Software? Hardware? POS?
