Submitted Question:
My computer won't recognize both cameras (I have them
connected with firewire). What do I need to do to get VC to recognize
both cameras? We want to start using VC for our daily news
broadcasts instead of Windows Media Encoder.
First question--do you have each camera connected to it's own separate firewire card?
This is a common issue that some don't know is a requirement. Explanation--your PC needs to see each camera separately, thus each camera needs to be plugged into separate firewire cards. On a desktop PC, these are known as PCI firewire cards and are under $20 each. Add additional cards when adding cameras. On latops, the firewire card fits into a slot on the laptop, but be aware that there are two types of slots (older PCMCIA and newer Expresscard slots). See my firewire card recommendations here.
In summary, just because you might see multiple ports on a firewire card does NOT mean it's ok to connect multiple cameras to it. Each firewire card represents a "firewire channel" to your computer. To avoid stuttering video, avoid plugging in multiple cams into one firewire card.
Hope that helps! Learn more about this in chapter 4 cameras of my Training DVD Volume 1. Let us know below by leaving comments...

Thanks for the info- I will purchase another firewire port.
