Well it's not checking for updates at the 1:30 nightly - none of the last few updates on either of my HWS were downloaded at that time, both were closer to 11 pm & midnight, interrupting my normal tv watching. Turned on tv & system was in process (for 20 minutes or more) on the 342 one.
Got a negative response from someone on the Dish forum about "still complaining", as he said the nightly reboots are the way Dish wants it & it will never change, it really doesn't cause anyone a problem ("it's only for two minutes!"). Can't believe anyone in their right mind doesn't see that as an issue. Having your paid tv interrupted everynight, every hour, while you are trying to watch is a definite problem for those of us who stay up late. Especially when there's no need for it to be at 1:30.
