There's a little trick that you could use: Quartz Composer can use

Irony: kineme.net specializes in QC Plugins ;) (the project I'm
working on is in fact getting 2 HV20's to work simultaneously in
QC). It can capture from one, or the other, but not both at the
same time. the built-in video input patch only lets you select one
(a Cocoa/AppKit bug), and our revised patch (unreleased) allows you
to select both, but when both are activated one camera never gets
its capture callback called. I wanted to make sure I wasn't making
some silly mistake to cause this, but it appears now that it's a
QTKit issue :/
Sounds familiar. It's probably rather a
looooooooooooooooooooooooooong standing sequence grabber skeleton in
the closet, still around after QTKit rebranding. IIRC for some
internal reason you could only access one DV cam for video in - for
everything else you'll have to resort to third party code (e.g.
starting with libdv).
No. This is no longer the case. QTKit can differentiate between
different dv devices and record from distinct ones, assuming you've
got the bus bandwidth.

The archives seem to have digital amnesia, I'm rather confident this
was already regular topic in the last milennium.
