Exactly! We did get a SDI signal, only not "good" enough for a Decklink extreme. We checked the signal on a SDI monitor, and we got a perfect picture. When trying in the Decklink Extreme, we got no input. The Decklink extreme apparently are more sensitive for weaker signals. We got a booster in the end wich cured all our worries. The Decklink standard however worked all the time.
