    Maybe I am having a placebo effect? But, to me. This new HR34 looks to have better pq then my HR24. Is this possible?

    Probably Placebo unless your HR24 is a HR24-500

    It uses RGB colorspace instead of YCrCb colorspace the rest of the DVRs use. Depending on your TV, it could look better, worse, or no difference at all.

    Every new generation of HD DVRs has the potential to include newer electronic components inside, including graphics chips.

    It's fair to say that as the HR24's and HR34's were released...they reflected some of the more current technology and have the potential to present HD as well as older models.

    That said, it still comes down to what actual HDTV you happen to connect up to the HD DVR as well.

    So I'm not the only one that's thought this! Exchanging my HR24-500 with an HR34- going to a Samsung UN60D6500- the colors seem to "pop"- really does seem to look better...

    To accept subjective opinion as real fact, we will need a lot of expensive professional equipment to proof it.

    The HR24-500 uses RGB colorspace while YPbPr is the standard and what virtually every TV expects to see.

    RGB 4:4:4 is 8 bit and YPbPr 4:2:2 is normally 10 bit, but can be 12 bit.

    As thus, the YPbPr would have more detail (2 more bit of data 10 v 8).

    So in that case, the HR34-700 at 10 bit YPbPr should look better than 8 bit RGB in the HR24-500.

    Winters,...
    Are you looking side by side with same source, lighting, and identical monitors? I recall thinking a software update over a year ago did the same.....

    In any event, you can make almost whatever pop by adjusting the Sammy's color controls.

    I see absolutely no difference between the 500s and 100s as far as PQ goes, but I've only got plasma TVs.

    It comes down to how the TV handles the different signals.
    I had to read about the -500 being RGB to know there was a difference.
    My Sony doesn't need any change in adjustments between RGB & YPbPr.
    I haven't tried this with my Vizio, but would guess I'd need to make changes.

    A cool test would be to have both the 34 and 24 hooked up to the same TV on the same channel. One could be in HDMI 1 and other HDMI 2.

    Then have another person who doesn't know which HR is in 1 or 2 say if they see any difference when switching inputs. Not exactly side by side but could rule out placebo effect.

    And then just to be sure, try it again and swap inputs 1 and 2 to rule out cables and inputs difference.

    That's the way I have mine, though I haven't bothered to ask someone else to check.

    Guess my plasmas just plain put out a good picture. I just checked side by side a 24-100 and a 24-500 on a 1080p set and I don't see any difference at all.

    I switched back and forth several times and saw no difference at all.

    That's the same as with my Sony. Sure it may put out a good picture, but part of it is that the TV adjusts to the type of input signal it receives.
    TVs that you can connect a computer to recognize the difference in type of input.

    Ah! So that's why my TV kinda jumps from a crappy picture to a good one when I plug my laptop into it?
