    Well said. I've found that those who complain about 3 watts are penny wise and pound foolish in their energy use. Further, if one is really serious about "green": update major appliances ever 2 years or so, but better still, don't use any, hand wash and hang dry, No PC, No TV, never use A/C nor central heat, and we could close down so many polluting power plants that we needn't worry about climate change and truly be "green" living off the earth as indigenous peoples encourage us to do. But if 3 watts makes someone feel "green" to justify and enable their energy hogging, air polluting lifestyle/devices, so be it.

    Just tune every tuner to a nonexistent channel, like 9999, 9998, 9997, 9996, etc. Voila! No buffering. The hard drive will still be spinning, and still do background maintenance tasks, but will never spin down.

    I feel this method does save a minute amount of electricity, due to not having to process the buffers, nor write the buffers to the drive.

    I sometimes make a manual repeating recording for each tuner of 1 minute each, for non-existent channels, and just place them at the bottom of my SPs. Since no signal will be there, no entries will appear in My Shows, and the tuners will stay "parked" until something needs to record.

    If anybody is holding their breath, waiting for TiVo to allow us to turn it off any other way, expect to die waiting. It's not going to happen, TTBOMK.

    I was thinking someone could make an automated process to autoswitch the tuners via a TCP remote control.

    This would have a 2nd use, of filling the live buffers with actual favorite channels, instead of the last tuned channel.

    KMTTG has it as a legacy function for speeding up transfers between old TiVos. It still works, but is limited to two tuners, tuning to what channels you select. It does change two tuners on my base Roamios.

    It's buried in the options as something that can be toggled to automatic, when a transfer starts, or by pressing the "test" button.

    I keep forgetting to ask if the author would be willing to make it support more tuners, and not require a transfer, or the options test, to use it...

    That could be more elegant because when I did a little experimentation last time this subject came up, it appeared the Tivo would ignore some kinds of tune commands via TCP remote, when it didn't have the channel number in the guide. (so i had to use IRCODE instead which worked).

    I am glad to hear Brian Williams say the cable and satellite industry have agreed to do something about their power hungry boxes. TiVo uses less power than many, but TiVo should also provide options to the user to allow using less power and shutdown or go into a very low power state if the user chooses to do so. There is no need to stay fully powered up all the time for many users.

    From the Roamio Hard Drive Upgrade Info thread, with some shared relevance to why we might want to at least have an option to limit Live TV buffering to a selectable number of tuners (read down in my reply to get to the relevance):

    As noted in one or more of my past posts, I came to the same initial impression.

    I feel it is worth noting that the AV-GP line, as originally marketed, did not include PVR/DVR use, only surveillance (It was added, not that long ago).

    One thing the AV-GP was never marketed for was NAS and/or array use, which the "Purple" is heavily marketed for.

    The numbers that truly matter are how many TB/year the drives are supposed to handle. I did the math on "unofficial" 120-150TB/yr RED NAS, and came up with "in excess of the rating", for four tuners at a modest 5TB/hr per tuner for high def. Even the published drives are rated lower than what a 4 tuner unit recording HD comes out to (~200 TB/yr). Do the math on six tuners.

    From AnandTech:

    "We had covered the launch of the WD Se hard drives for data centers and high end NAS units in May. One of the advertised aspects was the 180 TB/yr workload capacity. Western Digital is unable to commit to a workload capacity for the WD Red lineup because of the varying environmental conditions under which consumer NAS units operate. That said, WD expects (unofficially) the Red drives to be able to handle workloads between 120 and 150 TB/year."

    Whole article": http://www.anandtech.com/show/7257/...ed-nas-drive-lineup-with-4-tb-and-25-versions

    I'm seriously wondering how underrated a stock 500GB 4-tuner roamio AV hard drive is (IMHO, must be). The smaller the drive, the more each sector is overwritten per year, logically lowering the TB/yr rating, TTBOMK.

    I'm also seriously wondering how well plain Green, non-AV, non 24/7 marketed drives will hold up.

    It also would seem like (to me) one of the best ways to determine the true life (in P/E operations) of SSDs (Solid State Drives), is to put them into TiVos and see how long each one lasts, then do some math.

    From now on, I'll be trying to keep idle tuners on SD music channels. A 4hr recording of one comes out to less than 600MB (yes, MB) total size.

    If TiVo provided a way to stop live buffering, preferably with a way to specify how many tuners to allow to live buffer, I'd jump on it...

    If you're only recording prime-time while on vacation add a manual timer to cut power @ 12 or 1 AM and turn back on @ 7:45 PM.
