Hi, I need to capture two video streams from two DV camcoders connected to a Mac Pro via firewire. It's for a live streaming over internet, switching between two video sources. If I turn on both of the cameras I can still see only one DV-VCR signal on OS X. I think this is due to the firewire controller in the Mac Pro, which can handle only one video stream at time. So, could I find a solution buy an extra firewire adapter card? I found something like this: 4 Port PCI Express 1394a FireWire Adapter Card - 3 External 1 Internal http://www.startech.com/item/PEX13943-3-1-Internal-Port-PCI-Express-FireWire-Card.aspx Assuming that the adapter card is compatible with the Mac Pro, it should allow me to handle two distinct DV streams... am I right? Has anyone tried that? thank you in advance!
