    Two of the most popular hdtv capture cards seem to be the ATI HDTV
    Wonder capture card, and the Hauppauge WinTV-HVR 1600 card. People say
    the hdtv they capture is great, but I don't understand how it can
    capture true hdtv if they only have S-Video and Composite inputs. I
    understand the antenna input might get true hdtv. But otherwise I
    thought you needed RGB Component inputs, HDMI, or DVI? Can you really
    capture excellent hdtv through S-video?

    I'm not familiar with either card and don't have time right now to
    look up the specs, sorry.
    If the cards in question have but S-Video and Composite inputs, then
    they can only capture standard definition signals. They will not be
    able to capture high definition signals.
    In that case, yes, using a built-in ATSC tuner.
    Or HD-SDI.
    You can't capture HDTV through S-Video (Y/C) at all.

    You're recording via the ATSC-HD antenna inputs on these cards,
    not the S-Video ports (the latter are there as alternate/non-HD
    input sources).

    Oh I see so these cards are made to capture signals directly from your
    over the air hdtv antenna, satellite antenna, or cable feed. Do you
    know whether the newest hdtv satellite receivers have an output that
    can connect to this antenna input in these capture cards? I doubt it,
    I think the only way would be to capture a direct feed from the cable
    of these sources.

    satellite antenna, NO (DVB-S or S2)


    or cable feed. NO (DVB-C)

    It would do no good if they did, as the signal would be DVB-S.

    You can't work with a "direct feed" without a receiver. The products
    you mentioned have ATSC receivers.

    From a partially vaporware site:

    http://www.twinhan.com/product_satellite_1034.asp
    http://www.twinhan.com/product_satellite_s2_CI.asp

    Check out the their products listed on the left side of
    the page. For each one, look at the system requirements
    for the type of "antenna"/"dish"/or "cable" connection
    required.


    Luck;

  6. Different standards.
    Satellite uses DVB-S
    Cable uses DVB-C
    And Terrestial uses DVB-T.

    So your TV will become a monitor only over time, as you will always
    need some external device. TVs with DVB-T is sold here in Europe, but
    most people need a box for sat or cable.
