No. Not specifically USB. I just did not want to put 4 video capture cards
in the PC. In some systems, you are left with almost no PCI slots. I thought
USB would less obtrusive in this sense.

We already do firewire capture of digital cameras. And, I have seen a device
that converts a VHS signal into firewire digital video, but it was more
expensive than our target price. Times four.

We may end up with a PCI card and a manual channel selector. This is for a
calibration done on a periodic (every week or so) basis.
