    Well, the HR34 is finicky enough as it is without deliberately pissing it off...:D

    Do you give it a loving pat every now and then? Do you provide it with a cool dry place in which to rest? Do you talk to it sweetly?? Do you give it a strong signal, and......:lol:

    Please tell us how it goes/went.....

    C'mon, Ritchie... even bad/dirty power has no capability of creating artifacts whatsoever in a signal that is in the digital domain, so the rest of us also "have No Visible Artifacts on the Screen!!!" either, unless they might creep in during any analog signal handling in the TV itself.

    Not only that, but your APC UPS, which might save you from reboots due to dropped or browned-out AC power, will do nothing about DC power that is dirty due to problems with or aging of the DVR power supply.

    No but it does clean the AC Power going into the DVR and that is where most problems come from.

    Not only that but you can plug a hair dryer into a wall socket next to my HDTV and you will not see any Artifacts on the Screen due to the white noise in the AC Stream coming into my APC S15 but being Filtered out before going to my Home Entertainment System.

    Also, if you have a dying or Marginal Power Supply then you have a lot more things to be concerned about then Dirty Power coming from your DVR's PS because you are close to having your DVR Replaced by Directv and losing All of your precious Recordings. :lol:

    There are a number of things that can reduce issues after a restart.

    Since the entire device launches through a startup cycle - that includes the hard disk drive, as well as power supply and other components in the unit. There are never guarantees that all scenarios can be covered.

    One good general practice was referenced by RichieRich - a good UPS unit. While these do not prevent every conceivable thing that can impact an HD DVR operation, they do drastically reduce the number of potential problems.

    Clean power is your friend...so a UPS is simply a good best practice to improve the reliability and quality of almost any electrical device.

    In the real world, I've used 4 UPS units here in an area with power spikes happening from time to time, as well as one serious lightening strike in the general area. I was virtually the only home in the subdivision without any damage.

    Finally, at work...our company uses these to protect millions of dollars of computer equipment and other technology...so I'm guessing it's a smart idea.

    Yes, the best insurance you can buy. The DVR is a Linux PC, and you should protect all of your PCs and electronics with UPS's.

    How long following a restart should it take for the To Do list to be fully populated?

    I just rebooted and it has ten things instead of a couple hundred.

    Anywhere from an hour to 24 hours depending upon many circumstances.

    That's weird. Nearly two hours after the boot, it had about 18. This morning, it appeared normal.

    As it will fail to record shows starting 15 or 30 minutes after the completion of the reboot, I will now make sure to look at the To Do list after a reboot to make sure shows starting in the next few hours are among those immediately listed when the list is very short. When it had just ten listed last night, I don't think they were necessarily the ten nearest recordings; I noticed one was days later.

    I really havent ever noticed any of my HR's failing to record shows that were occurring in the next 15 or 30 minutes after a reboot. The whole idea of one of the last steps being downloading some guide data, and rebuilding the scheduler takes care of that. In fact, if a recording was supposed to kick off before the box is fully ready after a reboot, mine will actually start the recording right then and there. The to-do list is a like a living breathing entity. One minute you check it, even weeks after a restart/reboot, it will have 150 items in it, 2 hours later, 45 items.
