    Here is the mainboard. I do find it interesting that in the upper right corner, there are places for what I'm guessing is OTA tuners.

    One of the main chips. BCM4501KQME33G

    A secondary? chip. BCM5325FKQMG

    And the hard drive. Western Digital WD3200AVJS. 320GB Sata drive.

    Enjoy the photos.

    Here is the BCM4501

    Here is the scoop on the BCM5325...
    http://www.broadcom.com/collateral/pb/5325-PB05-R.pdf

    5 port 10/100 switch, hum!

    First guess is that the switch technology built in will let you daisy chain more than one together with only one connection to the router/gateway. This will make it easier and cheaper to connect the HR2x family together when in close proximity.

    I keep grabbing the heat sink with my mouse, but it won't move!

    Thanks for the photos. In the 4501 product brief, it shows that it is mated with the BCM7401 .. I'm gonna guess that the BCM7401 is under the heat sink.

    I'm looking forward to performance reports from you guys as I think the menus, etc. will be snappier than they used to be.

    They appear to be exactly the same as the HR20-700. If there is any speed difference, it's imperceptable.

    One more pic. It is indeed the BCM7401RKPB33G under the heatsink.

    The heat sink is "bonded" to the 7401 with a crappy piece of thermal tape about the size of a nickel. Thats been replace with a nice dab of thermal compound.

    Great photos RobertE! :)

    It's reallly neat to see the guts of the HR21 without me having to find my "special screwdriver" to inadvertently have my top come off to view it. :D

    Besides, the thought of me going topless here is causing my wife to have to down about 10 Tums as we speak. :lol:

    Clearly they are making some strides on the hardware side to compliment the firmware side.

    Thanks for the 7401 shot. That is what I was wanting to see!

    It's nice that it has the newer processor and all, but the performance is the same. Maybe they'll be able to tweak it in newer versions, but right now there is no benefit.

    There are probably a number of tweaks in the works. It looks like they took the HR20 0x168 firmware and didn't do much except grey-out the antenna setup section. It was a way to get it out the door and performance is already ahead of the initial HR20 firmware. I haven't compared the specs on the two versions of chip, but there will hopefully be a way to take advantage of the newer version.

    Since it is probably the same software team as is working on the HR20, they obviously have their hands full already and this one will be on the back burner for a while (although they may be able to bring it up to the current HR20 performance before long).

    Hope so. Forgot how valuable the Media Share GUI was to me.... :D

    It was interesting to look at the videos list in the old GUI. It actually showed my EyeTV recordings under EyeConnect. Of course it would be better if I could watch them :D

    If anyone wants to use the pics I took in a full blown review when its time to let the cat out of the bag, feel free. :)

    I've noticed that the INFO AND TEST screen generates much faster on the HR21 than on the HR20.

    Also, I don't see any green pixelation on the MPEG4 YES-HD channel when I come out of pause or FFW, unlike on either of my HR20s.

    That's likely the result of a better integration of the processor and decoder - things are just closer together.

    It's good to see that there are some performance improvements, though.
