    From BMD note:

    Can I ingest and playout at the same time with the Quad?
    The DeckLink Quad is basically four DeckLink SDI devices on a single card sharing a genlock. DeckLink
    devices are half duplex, they can capture or render, however they cannot do both operations
    simultaneously. Therefore on a Quad card, you could do 4 x capture OR 4 x playback, or
    combinations such as 2 x capture and 2 x playback etc.

    More information - appears that Decklink Quad only has 4 framebuffers, so you can only do two full-duplex channels, in other words, 2 in and 2 out independently.

    However I think maybe Millumin is querying the card for inputs and so automatically grabs all four as inputs, then the outputs are unavailable.
