    That's not true. Almost every computer by default spins down the hard drive first, then goes into standby.

    TiVo could do the same thing if it knew nothing was going to record (say during the night, ALL night. Or during the day, ALL day when I have nothing recording).

    So in your situation it may not be doable. It could be an option that you can enable or disable. I can see someone who doesn't record things during the night or during the day wanting this feature...

    way back in the late 90's my replay would wake itself up, record the show, then go back to sleep. all by itself. a decade ago.

    Huh? If TiVo's power supply can't handle a daily on-off cycle indefinitely there's something really wrong!

    ReplayTV offers an option to power down its HDD when in standby. Of course ReplayTV actually has a standby while TiVo just pretends. Perhaps its time for TiVo to consider offering an energy saving change in the normal way it operates.

    The other thing to keep in mind is there are 4 million active Tivo's today. If we could only get each one to shutdown for a few hours a day, the savings might save a (insert your favorite animal) someday.

    Wow, that must be torture on the hard drive. All those spin downs and start ups with the heads touching the landing zone on the disk.

    Most hard drives are rated for 50,000 start-stop cycles.

    If it starts and stops 10 times a day, you wouldn't have to worry for about 15 years.

    I guess if you define that as 'torture'.... :rolleyes:

    FWIW, I turn my computers on/off at least once a day, and still work. The HDDs are nearly 4 years old.

    Another issue is if as reported, Tivo is going towards a instance message model to communicate about downloads, or scheduling recordings remotely through the web, then Tivo would have to be on to respond to these IM. Maybe they can figure out a way for Tivo to wake up to such IM.

    Fact of the matter is, Tivo wasn't designed that way, ie, no on/off.

    Perhaps there was a time when Replay should have considered a change in the way it operated.;)

    I like my live buffer running all the time, my SA shuts the drive down due to inactivity, and every so often it'll do it when I'm watching just because I haven't touched the remote.

    Nobody disputes that, but SHOULD it be designed to save power...? Sure, why not?

    I stopped putting my DirecTivo into stand by because it stopped buffering, if they ever do this I hope they make it optional.

    The thread started out asking about Tivo's present capabilities.

    And I like the fact that I can power up the TV at any time and KNOW there will be 30 minutes in the buffer from whatever's running live on the tuners.

    My TV times itself out every two hours if it doesn't detect any signals from it's remote. This is a bit annoying as it meanwhile ignores any other IR signals (like to the Tivo) as a gauge of activity.

    I could see some value in having a user-configurable inactivity range. Sort of like being able to set a cell phone to silent mode at night. But a lot of programs I record are done at night, often as a result of the 2nd showing of a program while something else was on during prime-time. Heh, I guess my Tivo's most idle time would be 9am-5pm!

    Yes, something is really wrong. The S2 power supplies are way under spec'd and probably can't handle too many power ups, especially if the hard drive has been replaced. I don't know if the S3 and HD power supplies are better, but I think they are since the hard drives have since gotten bigger.

    Don't put the Tivo on a timer. If the hard drive's heads aren't in the safe zone when power is shut off, you can corrupt that file or destroy that specific area on the HD. It just happened to my kid's computer over the weekend (my two year old found the switch on the power strip). Windows now says those sectors are bad and the file that was there was corrupted, and it was part of the registry hive. The PC had problems booting until I fixed it. It rarely happens, which is why Tivo doesn't have a power-off menu feature, but you increase the odds of this happening by 200 times if you power it off daily. It's not worth the extra $20 / year in electricity.

    But yes, it would be a nice feature to add, especially if Tivo is supposed to be a high-end DVR.

    How about just subtracting the fuel that you would have burned going to the video store or the movies and call it a day? It's probably an annual net savings.

    There seems to be no end to the existential guilt in all of this "Green" crap. My Tivo brings me enjoyment and time savings....Yay! But it uses electricity....Boo!

    *Yawn*

    OO

    To clarify, as I am the OP... if I were having some sort of guilt ridden existential "Green" crap crisis as you put it, I wouldn't have three Tivo's would I? I'd recycle two of them and be asking if anyone knew how to hook my remaining one up to stationary bike so I could pedal it to get the hard drive to spin. My Tivo's bring me enjoyment and time savings too. The one in my gym only records late night shows and I only watch them when I work out in the morning. Otherwise it does nothing useful. I have no interest in shutting off the S3 in the den or the HD in the bedroom because usage patterns are different and less predictable.

    My view is that waste is waste whether it is energy, food, government spending, or whatever. Call it a pet peeve. If I stand in my kitchen at night I have four appliances telling me what time it is (Really Mr. Coffee, did I even ask you?) and lots of other things shining at me (especially if the laptop, Ipod, Blackberry, and Nintendo are charging). It looks like a Christmas display of LED's telling me they are alive. Does it waste energy? Yes. But more than that, its just gratuitious, pointless and stupid, IMO.

    yeah, right.

    I turn off all of my computers every night, and my Toshiba XS-32 (hard drive/DVD recorder) powers down the hard drive after a few minutes of activity (it's a user settable preference).
    I have had hard drives go bad -- in a Tivo ironically.

    I will put up with the increased wear and tear for the power savings..

    Can you give a citation for that 3 hour window? That sounds TOTALLY bogus.
