It can record perfectly fine through Linux, so it is not a hardware issue.
The computer freezes from simply using the card on Windows, as in any possible method I use to make the card display video causes it to freeze. I have tried anything from displaying in 1080i to 720p to 480i, it will always display for a few minutes and then my computer will begin to freeze. Then if I close out of the application that is calling on the card, my computer will blue screen.
I have tried using Media Express, Adobe FME 2 & 3, Ustream Producer, Adobe Premiere’s recording, everything causes my computer to freeze.
I am beginning to think that it works on Linux, because Black Magic Design seems to favor Max OSX, which is UNIX-based, so it was easy to make a clean port to Linux. Since Windows is DOS-based, it may be possible that when they ported to it something didn’t come over perfectly.
