This is likely a operator error on my part, since I'm also having the same issue on my second system using a BMD card with it as well (but on MC7.0.6).
I have tested a reel to reel tape machine on the analog inputs and a camera using the sdi input and I can't get picture or sound to come into MC8.5 usinf the DNxIO.
I've turned off machine control, the DNxIO is showing up in the capture tool, I've picked a bin, buth nothing is showing up on the audio meteres and no picture is showing up in the capture window. I checked the preferences in the BMD desktop video preferences and everything looks correct, but I'm getting nothing.
As a side note, nothing shows up in Black Magic express either, so it's definitely operator error, I just don't know what I have st up incorrectly.
Ideas?
Thanks.
