Well i just got a decklink intensity and a Sony HDR- V1P-

the V1P seems to be the first Sony HDV camera that does progressive scan,
Progressive scan means the input doesnt have to be deinterlaced.
and i seem to be able to get them to talk using HDMI - and get the input into catalyst.
Early days - but a good start.
