I bought a new Mirabox capture card (USB 3, 4K, Pass Trough, YUY2...) and I can't succeed to capture what I need or I don't know how to do it.
I go from a box (Cable TV) in HDMI to the Mirabox, Out in HDMI to the TV and Out to the Mac in USB 3.
In the Prefs system, I could select Input sound with Mirabox
In VLC, I could see and hear the movie, but for a reason I don't know, I couldn't record both.
What have I done wrong?
Can anyone guide me through this?
Is there a compatibility issue with my Mac from 2009 with Mac OS 10.9?
Thanks and happy new year
