Okay to follow up here. I am also running Windows 7 64bit. The only way I was able to get this thing installed was to first install the software/driver package, shut the system down and then install the card. Once that was done the system booted and detected the card and installed the drivers. I was able to see the card and use it in Premiere Pro CS4. The video quality was good but video/audio sync was poor. Also in some cases could play the first 2 or 3 seconds of video then it would freeze the player. But the file was saved in its entirety, I can scrub through the file but no player will play it.
Finally, when I rebooted the system would not reboot properly. I was forced to “restore from earlier” to get my system running.
I have sent a message to Blackmagic
More to come..
