What you see in this video tutorial is Capture Argo and not Capture Atlas. If you go straight to minute 02:20 Hebbe explains what are the options with the two driver versions available from MA.
Bottom line with Capture Atlas and on you need to have MA2 hardware in order to connect to Capture Atlas, and this is a decision made by MA Lighting. Of course this applies on the Capture Windows version, and not on the Capture MAC OSX version for which MA Lighting has no support for.
The best way to connect to MA at the moment is with Artnet or SACN from which ever Capture version/edition/platform you are running.
