I'm not confusing the different issues being discussed here... unfortunately I cannot count on being able to use the sdi input on the card.. and honestly id rather get to the bottom of this issue as this device works just fine capturing composite video outside of this. Can anyone tell me if any of the video is being buffered outside of the decklink card itself? I'm hoping moving the card will solve this issue but since Richard has had this issue and I dont know anything about that particular machines configuration I am not all that hopeful. so as of now the new firmware hasnt resolved the issue though PERHAPS lessened it and I wont know about moving the card until saturday at the next show. Is anyone NOT having this issue with this card?
