Yeah. Transmit is enabled in both the playback preferences and the playback wrench.
I'm getting bars from the Kona from everywhere else, but as soon as I open Premiere, it craps out.
In an unusual twist of events, I tried the card with After Effects and it worked flawlessly. Just another reason to think that it's something wrong with Premiere.
Odd, working OK with latests Premiere and my Aja T-Tap - can you post a screen shot of your Playback Preferences:
If you do the Setup on the Aja Device, anything amiss there?
Also - my experience with Aja support on a bunch of their devices has always been top-notch. Have you queried them?
EDIT: Have you tried trashing your preferences?
