I tried using an AJA IoLA. But in that case I was able to get playback on my video monitor, but NOT in the viewer. But I haven’t spent much time troubleshooting that situation. Were you able to get it working? If so, could you describe your setup? Does changing JPG quality percentage have any effect on the setup?
Right now trying out a Decklink (don’t know what flavor) and it works fine, but squeezes the image an extreme amount. I’ll start fooling around with the AJA!
