    While it is possible they save just a tad in standby mode, both the DirecTiVos and the HR20 are really on all the time retrieving data, listening for authorizations, waitin' to record that next show.

    Cheers,

    From a post a while ago, someone suggested tuning to a channel not received, before going to standby, to give the buffer a break. This post was for the hard drive noise. Could this also be used for the OP's purposes? Until it changes channels to record something of course.

    Why not do both? Also, most lights are not on 24/7.

    I don't really understand the resistance. If D* does this correctly, with minimal interuption to our daily routine (turn on time about equal to a couple of channel changes or so) everyone saves a little. Just because it isn't the biggest source of wasted power in our lives doesn't mean we shouldn't get rid of the waste - and all with no effort on our part.

    I don't really understand the need to micromanage. Improvements are constantly made in this area. Just not fast enough for some folks I guess.
    If the product doesn't meet your personal requirements then don't acquire it. IMHO

    IMHO, Slight monetary savings does not outweight the risk of losing program recordings due to failures to 'wake up'. There are some who use a second HR20 or HR10-250 to backup the recordings as it is.
    The whole basis on owning a DVR device is to be constantly working, updating guide data every 15min, and checking for recording conflicts. The mere ownership of a DVR is considered waste in most environmentalists eyes.
    Again IMHO, what is being asked is comparable to asking drag racers to use ethanol fuel to help the environment, or to put a filter on a good cigar to protect your mouth and lungs.

    Thanks. I was wondering if I was wrong about that. I was surprised to learn that the HR 20 never really turned off because I assumed that when I put the HR 10 in standby that it did turn off - or, at least, went into a low power mode. But I never really knew that to be true. And I guess it makes sense. As one of the posters put it, you really want this machine to be working all the time in a sense. I would also miss the buffer you get when you turn it on. I've used that a couple of times now where I turned the machine on, saw a show that had already begun I was interested in and was just able to hit record and get it all. Still, my sympathies are with the OP. If it could be made to go into a lower power mode and still preserve functionality, then it's a no brainer - gotta like that for the environment, for a bit of extra spare change in your pocket, for a lot of reasons.

    Way back in 2000 my Replay DVR use to turn itself off and wake itself up for scheduled recordings. I don't recall it ever missing one.

    Sometimes companies need prodding to do the right thing when somneone else is having to pay for their failure to act. In this case the customers are paying the higher electric bill so why should DTV care? Much like apartment complexes would have zero insulation if it wasn't required. After all the apartment complex owner isn't paying the electric bill so why should he care?

    If congress mandated tomorrow that DVR's had to reduce their electric consumption I have no doubt the next release would use 25% less power and we as customers would never notice a change.

    Did the replay actually save power during the standby mode? Did you mind that the buffer was flushed when you woke it up?

    That is the trade off (which could be put into an option, of course). Buffer everything or save power.

    In the case of a satellite DVR, the unit is always receiving data you usually want: guide updates, authorization updates, and standard dvr buffering. But if you preferred, DIRECTV and E* could setup options for disk power down and tuner power down that would affect the overall dvr experience. Guide data might not be fully populated out to two weeks. Buffering of the channels would be gone. And wakeup would likely be longer as the LNBs had to energize and settle.

    All this could be done. And for some rooms, I might set them up to do so. But the most heavily used rooms, I would not.

    And has been said before, there are likely much bigger fish to green first. (Tho I did get gas water heater and clothes dryer when I bought this house.)

    Cheers,
    Tom

    I know this would be a HUGE sacrifice, but if you are that concerned about the power consuption, maybe you could somehow live with only 6 DVR's instead of 7. Reminds me of the millions of people driving their SUV here, there, everywhere, all day long, and complaining about the price of gas and acting all concerned about global warming. Spare me.

    Well, thank you for singling me out. Can you tell from the information I posted what other measures I have taken in my life to reduce my energy consumption? No? Then please don't presume to know me and pass judgment. Really ... spare me. :rolleyes:

    At one time the government did 'energy star' certifify set top boxes. That is if a set top box used on average 25% less energy then the norm it could get an 'energy star' logo. But I believe the set top box makers argued that the technology required all set top boxes to be on 24X7 and the technology was so similar there was no room for any manufacture to really gain an edge. So the 'energy star' program for set top boxes was scrapped.

    My set top boxes are mostly inactive midnight to 5pm most days. My $29 clock radio reliablly wakes me up in the morning and only uses 2 or 3 watts. It even has a weekend program. Again, how hard could it be to put some logic in these boxes to wake up to record a scheduled show, download guide data, or other scheduled maintenance and then turn back off? Sounds pretty simple to me.

    You and others are ignoring the "buffering" feature of DVR's. It may not be important to you, but it is to many. The DVR must be on or in standby for this to function. I suggest a regular set top box and a recorder of some sort with a timer function would better suit you.:)

    There's no reason it couldn't be optional.

    It could also wake itself up every 24 hours to check for sat updates even if nothing was scheduled to record.

    The key would be making the "wake up" instant. Users can't be expected to wait for the thing to boot up.

    How about a user setable window for when the dvr may shut itself down to save power if no one appears to be actively using it. Buffering will be lost. If users enabled it from 12 midnight to 6 am that alone could save 25%.

    Assuming for the sake of argument that this mode of operation won't be a problem for other DVR features and operations, why not use an appliance timer. Seems like that would use even less energy than the "wakeup" circuit would on the receiver.

    Cheers,

    Then it couldn't wake up long enough to perform scheduled recordings.

    It's optional now. Unplug your DVR when you're not using it.
    If approx. 30 watts is too much for you I hope you don't have any electric clocks, your tv's plugged in when not in use, microwave unplugged till needed (that clock is eating power), and air conditioning is definitely out.
    I could go on, but at this point I feel like I'm....
    :beatdeadhorse:

    (P.S. To me having a DVR shut down makes as much sense and having my refrigerator shut off until I open the door)

    corrected to post, not reply

    I think we have come full circle to a huge problem with the HR20. It can't tell time without the link. If you put it to sleep and go to low or no power, it will be no different than unplugging it. Before we ask for an energy saving function, we should concentrate on the wishlist item "The ability to watch recordings when there's no satellite signal". Without that, the hopes of energy savings is a mute point.

    I wasn't actually asking for it to be implemented. I was just pointing out that you could easily save 25% of the power consumption if you wanted to.
