Ok, I will try and post a support PDF.

To answer some question, Brand New Mac Pro (came in 2 weeks ago)
8 - 3.0GHz core
2GB of Ram
32GB Mtron SSD
Nividia 8800 ( I think that is the graphics card, I am not in front of it right now)
OS 10.5.4
Catalyst m165
Decklink Extreme HD 6.8.1.

I have it in slot 2 right now, because when I put it in slot 4 and then put the catalyst in full screen, the second bar at the bottom ( sorry don't remember what it reads ) goes all the way up to 200% and every movie I have plays back at 15FPS no matter what format or size it is in. At one point i got the signal using the Blackmagic deck control software, but when I closed that and opened Catalyst, still nothing. I think the signal source may have not been right. After this show is over, I am going to look into it more. My bigger question is why Catalyst starts playing back slow when I put the Decklink card in the top slot. Do you think it has something to do with OS 10.5.4? If so, how would I get a copy of Tiger?

Thanks for the help.
