According to this page:

Their SP card should work on the PCI machine. The operative text is:
> “Short” PCI 66 MHz card, fully functional with PCI 66 & 33 MHz
> slots and PCI-X 133 & 100 MHz slots.
We bought one, based on that, and guess what? It doesn’t work. No video output. Tech support claims that Apple owns the problem and that everyone else is having the same problem (see below.) After much discussion, however, he admited that their (Blackmagic’s) webpage is wrong and should be changed.
In the meantime we are sitting here with a brand new machine bought to Blackmagic’s spec and a full load of software, and we can’t output to video.
Still waiting for Blackmagic’s sales guy to return my call. In the meantime, I’ve talked to AJA. Their sales person was very interested in hearing about this problem. He told me their LS card will work on my system. It costs about $400 more, but maybe it’ll actually work to their published specs…
