Just adding to the conversation, yesterday I checked my DVR and it used 47W in Off/Standby and 50W when ON per my Kill-A-Watt meter.
If you basically recorded prime time TV and also changed the default 3:00am update time to an earlier time, is there any reason why you could not use a regular light timer & power off the DVR for 12 to 15 hours or more? Just make sure the DVR powers up in enough time to acquire signal before it needs to record.
The issue would be when you don't want to record prime time TV ... or the "one offs" which do happen more than people might admit .. pay per view events ... or people with Sling Adapters ... certainly a wakeup on lan type option would hopefully allow the unit to go lower power and then come up to do things ...
And then there is the whole "remove power" ... technically that's what the physical power timer does ... it cuts power from the device .. that isn't going to harm something like a toaster, a microwave ... etc.. but when it comes to some devices it could really harm them.
Recent reports show that quick cycling compact florescent bulbs shortens their lives... its long been known that incandescent bulbs blow either at power off or power on ... so certain devices need to have a "better way" to apply or remove power.. and Dish Receivers do fall into that category ... as they have a physical moving device inside.. the hard drive. It may not be actively writing anything... but it being given the command to park for power off... and emergency park for power loss can be different. And that's part of the whole "windows shutdown" so that you don't lose data ... you flush cache, go park, power off..
I cringe every time I must pull the power on my receiver.. because I know it could glitch out, it could wipe the drive, it could die .. and low power states help alleviate that fear ... but an external "cut" to the power is dangerous.
And from another technology ... removing power from a soft power device .. like most bubble jet printers.. will kill your supply of ink. On power up, the printer will go through a longer cleaning routine to make sure it doesn't have clogs, etc.. because the printer doesn't know how long it was without power and there seems to be no capping method that would preclude long cleanings..
different technology but again why hard line power killing can be bad ... low power states good .. and Dish *could* do more to lower the power during non-crucial times. Hard drive does not need to be spinning 24/7, LNB does not need 19v power 24/7, unit doesn't need to check every 5 minutes for updates/fixes/etc, especially if the receiver is internet connected
ie. with 20 different models of receivers out there, 20+ different firmwares, different guide data formats, etc there's an arguement that the receiver needs to be listening to know when *its* turn is, but on internet connected devices, it could check there once an hour, "oh your update time via satellite is in 35 mins" and issue wakeup timer for 25 mins from now.. etc..
you just have to think alternatively, and dish doesn't do enough of that.
