Definitely file a bug. You should only see a 2 or 3 frame delay with
one card.

Hi.
So weve done some quick tests, and the results are not too promising.
Test rig:
Mac Pro Dual (Dual Core) 3Ghz
8GB ram
Mac OS X 10.5 - clean install, with Dev Tools
Intensity Drivers 1.8
Quicktime Pro 7.2.1
2x Decklink Intensity PCI-E cards
No odd quicktime codecs or other software besides Max/MSP/Jitter
Quartz Composer still retained the lag. We did not do any concrete
frame accurate testing, but it seemed on par with previous versions
(it still went from laggy to not so laggy, to almost snappy, back to
one or two seconds behind). Interestingly, Quartz Composers video
input patch only listed *one* Intensity input, and seemed only to
use the *second* card. We could not switch to another Intensity
source.
Blackmagicks On Air software was able to recognize both Intensity
inputs and showed no lag what so ever.
We also tested Cycling74's patching environment, Max/MSP/Jitter, and
were able to list both Intensity cards as input sources, and showed
no lag.
So, Im not sure whats going on, or who to speak to for resolution. I
will be sending our reports to Blackmagic for confirmation.
Does this look like a bug? Should I file one officially?
Thanks,

Hello.
Has anyone tried out the Decklink Intesity card with the latest
release?
Vade reported a 45 frame lag with a previous release:

Of course, getting an input from two cards simultaneously would be
a god start for a great HD
mixer!
Thanks for your work.
