Sorry for coming in late, guys,
someone was pointing out that thread to me.

Dylan, I would be interested in knowing how you
actually do that, splitting a signal on two or
more projectors (from a laptop?).
I have done a 7 dvd installation before, and had
to use the equipement that was available (all
different players), with differences of up to ten
minutes by the end of the day. (Each player takes
a different time to operate the loop command).
And I am doing double projections of high rez
quicktime slide projections, where I found a
solution with running it from two MAC minis,
using the remote to start them in sync (not
always easy but possible) - once they are in sync
they really stay there even over two days (which
happened once, the gallery turned off the
projectors but not the computers)

However, I did not find a way how to have two, or
more (I am aiming for three) movies run from one
computer. Quicktime and other applications would
only do fullscreen on one monitor, even if you
are able to run two seperate monitors, and that
is only two, not three.
Do you need extra hardware, and special software? (I am on MAC)
Does the file have to be one movie (which would
require a special oversized format as output and
would have to be run from quicktime, which does
not run without creating artefacts), or can it be
seperate movies running on one computer?

thanks for the discussion and your possible advcice
