Greetings.

Here's what I am up to. I have just built a studio, small but jam packed with goodies including a video setup. I have three cameras, two remotely controllable, and one that's to be hand held. The studio is a fully functional recording studio, but I am also going to be doing in order, both live audio streaming through my own internet radio station, and soon streaming video content as well. Here's what I have right now:
Custom built PC, I5, 8 GB ram, 64 bit W7,GeForse GT220 dual head graphics, lots of sata based storage.
Camera 1 - Canon GL2 feeding into the computer via Firewire.
Camera 2 is a Sony D30 remotely controlled using BDLCam - this camera feeds a composite signal into an AVS Pyro AV Link box which inputs into the same computer via a second firewire port.
I am adding a Black Magic Intensity Pro PCI-e card for a third input from another Sony D-30. I also have a outboard SMPTE generator to sync everything.

Question
Will I be able to record all three camera's at once? (have not tried yet)
Is there software available that could be used to MIX the video signals for a final output. I have been considering upgrading Arkaos to the latest version. But wonder what's available for this.
Is there capture software available that handles multiple inputs at once?
What are the best video conversion programs?
Where are all the capture CODECs? (See other post in Capture)

Any advice, help, links, comments or suggestions would be highly appreciated.

Thank you.
