I was intending to buy the Intensity Pro card for monitoring an HD timeline from CS3.
The files would have been AVCHD material converted by Neo Scene. I have no intention of actually capturing material via the Intensity card - only monitoring via HDMI out into an HD tv.
I understand that natively captured via Firewire HDV files will play out OK, but how about the Cineform files?
Another question: How does Premiere recognise the new Intensity hardware? Is it automatically showing up in the CS3 menu? - or is there some software that comes with the card?

I believe at this point the Intensity will not output Cineform files in realtime, but that is a feature that has been promised in the future and many are looking forward to.

The only formats that the intensity will output in HD are the MJPEG and Uncompressed.

For cineform files you may need something more substantial. I thought that the Cineform folks were big fans of the AJA Xena cards. I can't recall if it decodes cineform in real time though.
