    I am able to try the test - the screen blanks - the receiver seems to switch modes but nothing displays - Finally it goes back to 1080i and it says my TV cannot display DirecTV's 1080p...

    Ok, (thinking out loud here), the HR2x is switching to 1080p24 and sending a 1080p24 signal out. Sounds like something is not sync'ing to the 1080p24 signal stream. Either the AVR isn't accepting it and passing it on (or isn't re-scaling it) or the TV isn't accepting whatever the AVR might be doing.

    A slim possibility is the hdmi cables, but if the same cables worked to the PS3, I highly doubt that.

    Cheers,
    Tom

    That just doesn't make sense though - why does the PS3 work at all in the same configuration and not the HR2x? Again - it points back to the HR2x...

    Since I do not have any 1080p TVs, I can't verify anything. I'm working off the collective of experiences I've read about. That includes PS3's love to upscale to 1080p60 which is supported by "most" "1080p" TVs; yet one can be force them to 1080p24 for this kind of testing. And includes lots of AVRs can block a proper hdmi handshake or hdmi signal, if configured incorrectly (which is easily done).

    So I can't actually test any of those configurations. (That's what I get for being early adopter enough that all my TVs are 1080i.) :)

    What we're left with is experiment, find the real issue, and dig for the configurations that really work.

    I'm fairly willing to believe that your equipment should be able to work with the HR2x (it is new enough and pioneer kuro/elite hasn't been high on the problematic list). Since the TV likely doesn't have many settings that would likely get in the way, and AVRs are often full of features and settings, that leads me to try finding a setting there first. (Or even a firmware upgrade for it.)

    Cheers,
    Tom

    All 50 inch and larger Kuros should work. My PDF-6010FD (non-elite Kuro) works OK.

    I think if you have an AVR in between, you need to check it out. I had issues with an AVR and had to go direct from the HR20 to the TV and use optical to the AVR to get audio. Later CE firmwares fixed my AVR issue, but I still watch directly connected to the TV, as it is more likely to work.

    Many AVRs can be set to process the video to a particular resolution or pass it through unaltered. You need to set it to pass unaltered.

    Through the CE process a lot wanted to see blame in the box, and perhaps there is some there, and perhaps DirecTV is being over cautious not 'forcing' 1080p/24 mode. But I bet DirecTV doesnt want the support load of having to unset 1080p on DVRs hooked to tv's that dont support it but now only showing a black screen because someone forced 1080p on a set that wont do it. So they are adhering to spec, if during handshake (and all HDMI connections handshake otherwise there is no data transfer from what I have read) the TV doesnt say it supports 1080p/24 D* isnt even making the mode avail. That said, probably the most valuable piece of troubleshooting you can do is hook the HDMI cable from only the DVR directly to the TV. Reboot the DVR and see what you get testing.

    It's like Tom said a lot of TV's dont handle the handshake well. Some TV's who can clearly prove using other devices that they will accept a 1080p/24 signal in, do not claim to support 1080p/24 during the handshake. (one CE member proved that with his Vizio). You can also check with your TV manuf for a firmware update, some people had success with that too. If your TV can support 1080p/24 forced from another device but doesn't handshake saying it supports 1080p/24 then this is your only recourse at this time.

    For the uninitiated HDMI devices when powered up send out a signal on the cable that says roughly, "Hello device on the end of my cable, what modes do you support?" and if its a device with HDCP "Hi device on the end of my cable can we exchange Encryption Keys to display protected content as well?" Note that while you can display HD content over the component cables, HDCP will not function due to the lack of any handshake, this is a DRM issue that will never be fixed as its intentional.

    Is there a way to see on the receiver, either on the front display or on the OSD, what resolution is being fed to it? That'd be something worth trying.

    So after all this technical talk I have determined that my Sammy is supporting 1080p from the D* box. Now, where or when can I download a 1080p movie. You would think with all the hype they would at least have a test movie to try. :confused:

    I have a Sony 60A3000 which does support 1080p/24.

    My HR21-700 switched to 1080p with no problem but my HR20-100 failed the test.

    Any ideas?

    My pioneer elite 50" plasma (pro1130hd) "accepts" a 1080p/24 signal from a PS3 just fine (both directly and through my hdmi a/v receiver, but displays at 768p/72. This is achieved by forcing 1080p/24 output from the PS3, since it probably doesn't pass the info via handshake. I wish D* would give a "force 1080p/24 output" like the PS3 does. To cut down on confusion among users, it could be buried in the menu system somewhere or even implementable by hidden "keyword search" terms. If it's an option for PS3 seems like it should be for my HR20-700 as well.

    Your Samsung doesn't happen to be a DLP set? Post your model number as Samsung LCD flatpanels have had no problems with 1080P movies and fully support all 1080p refresh rates.

    The Samsung DLP's have been a whole other set of issues.

    I have the same TV, and it does indeed support 1080p/24... but the HR2x does not recognize it... When you try to enable the 1080p resolution and the screen goes black, just go ahead and hit the "Info" button to confirm it... And once the HR2x outputs 1080p material to it, the TV does recognize and display it correctly...

    AVR receivers are notorious for HDMI compatibility issues, even the most expensive ones seem to have a problem getting it right. If it works connected to your tv directly, the issue is your AVR, regardless of other equipment working.

    You certainly aren't kidding there. I don't think there's a thread at AVS on a receiver line that doesn't have someone complaining of a handshake issue at some point. At this point, you just have to accept that some configurations don't work despite the fact they should. It shouldn't be that way, but it is.

    I just tried to get my HDTV and AVR working with release 290 on a HR21-700. No luck. Sony 52XBR4 TV with Sony DA5300ES AVR. PS3 works fine with the AVR and TV and yes I have seen the TV display info showing its running at 1080p/24 as well as 1080p/60 based on various content.
