    Comcast digital cable in the NW. Since MCE has to use the same EPG for its
    input is there any benefit to a dual tuner like the Hauppauge 500 if it's
    being fed by a cable set top box? Any way to 'split' the signal to the two
    tuners? Thanks -

  2. Hi John IV,

    As HillBillyBuddhist has stated, the only way to get dual tuners to work
    with digital cable is to have two set top boxes (STBs). With digital cable,
    the tuning/decrypting is done by the STB. Most STBs only have a single
    tuner in them so you need two STBs to get two channels going. The signal is
    then passed to the TV tuner card(s) on the computer. The tuner cards are
    "tuned" to whatever channel you would tune your TV to when connected to the
    STB (could be channel 3, 4, s-video, etc). Have two STBs also means you
    need two IR blasters because of course, the channel changing needs to be
    done at the STB, not at the tuner card. This is something I have not done
    myself, but I hear it is possible. You do need the extra IR blaster though
    (The IR blaster is the cable that goes from your computer/MCE IR receiver to
    the IR receiver on your set top box to relay the channel changing
    directives).

    Let me know if you have any further questions.

    A Hauppauge 500 does not have two antenna inputs( it uses an internal
    splitter to its two tuners for an antenna or cable input out of the wall so
    you can not use the RF connectio (channel 3 or 4). To use two STBs with the
    500 you have to get the 500 daughter card (which uses a PCI slot) so that
    you can input to both tuners using S-Video and audio. The S-video input also
    produces much better PQ than RF also. The NCIDIA 2 tuner NVTV card has 2
    S-video inputs so a daughter card is not required for 2 STBs.

    Understood, thanks all. I assume the Hauppauges (150 or 500) have at least
    a single s-video in right?

  5. The 150 has a single S-Video in, the 500 has one, but also comes with an extra backplane board for additional AV connections.

  6. At this time there is no benefit. Hopefully a future version of MCE
    will allow independent EPGs and input signals for multiple tuners.
