We are having problem using the latest system update OS 10.5.4, decklink 6.7.2, and Final Cut Pro 6.0.4. the video freezes on playback using the preset of blackmagic 720P 8 bit using the blackmagic 8 bit 2 Yuv using a 30 terabyte SAN for RAIDs. The update as renders the application useless as far as mastering to tape or customer preview. Just my post for OB..
