    If Duracell batteries are considered "challenging" in a remote, I an only imagine what some must think of this challenge ...

    I just need to get an idea of the mechanism that might cause this.
    "I mean" this is a battery, which is so basic in its function.
    It doesn't have "noise", nor can it radiate anything.

    I have read that some batteries or battery compartments don't alwaly fit together properly and you may get odd results but I haven't run into that personally.

    Eveready claims you can't [shouldn't] mix & match batteries, as leakage might be an issue. If you changed only one out of two, this might makes some sense.
    "The truth is", a AA has to meet physical & electrical specs to fit devices.
    Their voltage is defined by the materials used, as it's a chemical reaction [and you can't change the laws of physics].
    The idea that one maker's battery causes problems while another doesn't, would seem to come from the user not measuring the battery condition correctly and "assuming" a semi discharged is in better condition than it really is.
    Duracell used to supply a tester in the packaging, which loaded the battery.
    Simply measuring the voltage without load will give a false reading.

    The part that got me was how a battery could affect some keys, but not others, on a remote control.

    This could/might happen with a semi discharged battery, but the same would happen with another maker's battery too.

    It's possible that really cheap batteries could be under voltage, or if you're using non-alkaline batteries they may just drain too fast.

    You're on the right track here, but you're really saying the same thing.
    "Fresh" cheap batteries will have the same voltage.
    How long a battery lasts comes down to the power density [materials used].

    As the chemical reaction decays, the static [no load] voltage will be the last indication, where the loaded voltage would be the first.
    If the battery can't supply enough electrons, the voltage will drop.
    I think all of this comes down to batteries in their marginal condition/state.
    Cheap/crappy batteries will drop off line faster than a better battery that has a longer "marginal" state.

    if you look at a duracell battery the positive end is slightly larger and flatter than alot if other brands. This causes the incomplete contact and lack of complete charge throughout the whole battery

    I just did compare a Duracell with four other brands [those that come with DirecTV receivers] and while there are slight differences, the only major one was that the others have a slight point in the middle of their positive contact.
    "If your device's contacts" aren't clean and have less tension, "then" this small point of contact might make a difference.
    If, on the other hand, they're clean and have good tension, then this is meaningless.

    I guess what I'm really saying here is:
    Don't use Duracell if you're not going to inspect/clean the contacts, or have peanut butter on your hands while changing batteries. :lol:

    Never had that happen to me and all I use are Duracells. Can't help but wonder which buttons are adversely affected. Even extremely crappy batteries are problem free for a short period of time and then they run out of juice. Is there something mysterious in the DC voltage that the Duracells induce in the remotes? Or is this a joke?

    Ohh, I know! It must be the frequency of the DC voltage of the Duracells!!! I'm sure we all know how delicate the frequency of DC voltage is...:lol:

    I SOLVED IT!!!!! Bought a logitech IR repeater. Once I block out the DTV dvr from ambient light, and put it near the IR emitter, IT WORKS PERFECTLY.

    Clearly the IR receiver has a firmware or hw-related issue on this dvr that makes it susceptible to ambient light. In my case it was either sunlight through a window (not even that bright) or incandescent light from 2 bulbs in the room.

    It works 100% of the time with my jury-rigged IR repeater setup. Now all I need to do is make it more permanent and aesthetic.

    Thanks for everyone's comments, and I hope this thread (and the other one I have open) help others solve their IR problems too.

    These Direct TV dvrs dont work well with ir extenders. If the ir sensor on your hr24 sees the ir from the remote and the extender at the same time the hr24 will not respond to the remote. I had this problem with an ir extender. You need to use ir extender ir leds and place one over the sensor location on the hr24 and then cover it with something to block any ir from the remotes ir led from getting to the sensor. This is tricky to do as the ir pickup in the hr24 is very sensitive.

    How tricky is it? Took me one pie plate and 5 minutes for a simple test, and it works perfectly. I'll just make a "cover" that holds the IR emitter that blocks ambient and DVR-remote light from hitting the DVR.

    In my opinion, the IR repeater SOLVED the problem, and that's pretty much all I care about. Now I can use my universal remote as I had with previous DVRs, and we can migrate to a new remote if we want.

    My wife loves how well it works (as do I), so that's what really matters, no? :)

    I can't believe that statement about the Duracells was posted. What was that poster thinking?

    Some "specifics" would be nice to see. Anything to make these claims a bit believable.

    Kinda hard for me to believe what he was saying without some Facts to back it up!!! :D
