    :shrug: .. Anything is possible, but it depends on what the installers in your area have in stock and on their trucks.

    I would still like to hear whether this product uses the new, faster BCM7335 or the older BCM7401 like the HR21, HR22, TivoHD, and Dish ViP612. All of these other products use the same Broadcom drivers for audio and video.

    If the HR23 is still using the BCM7401, with the same amount of memory, then I find it highly doubtful that it would offer any improvement in digital audio or digital video output. Different driver parameters could always be used for audio and video, but I don't see why DirecTV would do that for one BCM7401 product and not another.

    Now, if this product is actually using the newer BCM7335, then it would be more inclined to believe that differences people are seeing and hearing are real. Even then though, I would caution against saying the picture or sound is better; different doesn't necessarily mean better, just different. I've seen cases where a driver for a new chip produced what some perceived as superior sound, when in actuality all it did was increase the audio levels (volume) slightly.

    I would like to second the statement about the concern about the 100 series boxes!

    DTV sent me an upgrade HR21-100 and a H20-100 replacement for my recalled H20-600. After I activated them both I did side by side comparisons on differing inputs on my two Sony HD Crts and my DLP Mits to my other HR20-700s and then to my recalled H20. The PQ on the 100 series boxes is noticably softer and not as sharp as my HR20-700 and H20-600.

    I'm acutally quite relieved because I drove around to Best Buys and Costcos all over my area looking for a HR21-700 and all I could find were HR21-100s and HR22-100s. If this continued long term I was panicing thinking about switching to FIOS because my HR20-700s are a little hot and vibrating more than normal. :)

    Horray for a new PACE box!

    It's been a while since I've written on the boards but I'm still holding out for the day when an HR2x box can handle the tuner switching from within the box. Running the second cable is a pain. Heck, I thought we'd see a triple internal tuner switcher by now.

    wistex, if you have a SWM, you only need to run one wire. All HR2x receivers support this.

    We've got the two-tuner setup. It's called SWM - Single Wire Multiswitch.

    See this guy...

    The following quote from the First Look seems to imply the same processor:
    "As far as performance, I have seen different speeds at different times. Most of the time the HR23 seems to run as fast (if not faster) than my HR20-700. However, there are times where the menu and guide navigation drag a little."​
    Would expect the newer processor to be considerably faster ... but still hopeful.

    Is the HDMI OUT - Version 1.3?

    TKS:confused:

    Since the HDMI spec was just released in June, not very likely.

    It is definitely not 1.3.

    Well, you know, there's more to unit speed and responsiveness than the CPU. My HR20-700 absolutely flies compared to my HR21-700 and it always has. We've wondered since Day 1 with the HR21 why it's a relative slow-poke compared to the older HR20.

    People with the TiVo Series3 (same BCM7038 CPU as HR20) and TivoHD (same BCM7401 CPU as HR21) wondered why the older Series3 unit seemed more responsive and provided superior network throughput when transferring recordings between DVRs.

    Linux benchmarks run on hacked units determined that memory bandwidth on the older BCM7038 (in the HR20 and TiVo Series3) was significantly higher than the BCM7401, despite the fact that both used DDR400 memory with the same latency. The BCM7038 also has a dedicated FPU whereas the BCM7401 has a emulated FPU. Both chips run at the same 300MHz clock.

    Broadcom does offer a much faster variant of the chip (BCM7400), but I'm not aware of any product that uses it.

    Great job guys as usual :) But what bothers me is D* has all these different receivers, but when it comes to them working properly there always seems to be problems :confused:

    June of 2006 that is. There are a lot of devices that support 1.3, with HR2x's not being one of them.
