    Newb here, did some research on my question but couldnt find an answer here so I apologize if the question has been asked already. Just had the 622 installed in my home, receiver connected to an HDTV via component (main TV), the RF output on the box is connected via coax to my in home cable wiring providing a signal to a 2nd TV also an HD TV. So far, I'm very happy with all the HD channels, the guide is great, DVR easy to work, etc., etc.

    Before the Dish install, I had the main TV connected to my old Cable HD DVR. The 2nd TV was connected directly to a Coax cable in one of the bedrooms. The 2nd TV has a built in QAM tuner so when I first brought it home, I simply connected it to the coax, the TV searched for and found a variety of HD channels that I was able to view without a problem. Now, I get no HD reception on the 2nd TV. I'm assuming that, without another box, this will not change but I'm interested in knowing why.

    Anyone? Thanks in advance for the help!

    The 622 only outputs SD to TV2, and unlike cable, it is not capable of carrying HD over coax. QAM is not transmitted over DISH. The 622 runs 1 HDTV and 1 SDTV. Additional SDTV's can be mirrored via coax through a home wiring connection.

    If your second TV (TV2) is nearby, you can view HD on both TV's by using both the component and HDMI outputs on the 622, but you would be viewing the same channel on both TV's.

    Or you could get a component or HDMI splitter like I did. Also, you would be viewing the same channel on both TVs.

    I may be missing something here, but your HD TV connected to a CableTV signal would not receive HD signals unless you TV had a CableCard in it. Someone please enlighten me if there is another way to get HD besides the following:

    DISH HD Receiver connected via component/HDMI/DVI

    DirecTV HD Receiver connected via component/HDMI/DVI

    Cable Box/CableCard (Motorola, Scientific Atlanta, TIVO, etc, must be HD) via component/HDMI/DVI (Or built-in CableCard of some models)

    Over the air (OTA) via antenna, connected to a HD Digital OTA Tuner (set-top-box via component/HDMI/DVI)

    Finally, Over the air (OTA) via antenna, connected to the input of a TV with a built in OTA HD Tuner

    I did not think it was possible for a TV with a built in HD tuner to pick up HD channels over cable, although the HD channels may look better than standard def, they will not be in real HD.

    Just Curious...

    You are missing something, so I will enlighten. ;)

    A cable card is an authorization device. It is not a tuner. Cable companies send some of their HD unencrypted (all locals for example) "in the clear." All you need is a QAM tuner and you are good to go. It is uncompressed and looks awesome.

    If you have a QAM tuner built into your tv you can get any of the unscrambled HD channels right off the cable. These are usually the big networks ABC, NBC, CBS, Fox and PBS. That is what I do. No extra charge even. Just plug in the cable and enjoy.

    You only need a box/cable card for scrambled stations.

    never mind John answered the question
    I believe he is talking about the QAM tuner. You can get the unencrypted cable (HD) channels without needing the cable card. (i.e. local channels)

    Hello Lujan (or others),

    I would like to do what you are doing regarding an HDMI splitter. I am looking to purchase this one from monoprice:


    I want it to drive my two HDTVs in two separate rooms. The main room, where the 622 DVR is located, is a 1080P monitor. The second set is 720p.

    It seems that an HDMI splitter, like the one above, would work based on your post. I am concerned though by a few things:

    1.) If you go into the Dish setup menu, it shows you details about your HDTV. Obviously there is two way communication going on here. If there are two HDTVs connected, how will the DVR know which tv to show details about? Will it confuse the receiver?

    2.) I read somewhere that HDCP doesn't work with a splitter like this. Would Dish be problematic in this area?

    3.) Any other negatives? Is HDMI really defined to properly support multiple devices on it or is the splitter a hack of sorts? I wouldn't be concerned if it were a unidirectional link but, being bidirectional, I am worried about both tvs driving the same signals at the same time and messing things up.
