Synchronized video play-out over 2 dvi-out ports

[bertoa]

How to play out 2 video's from 1 system over 2 DVI-out port from 1 videocard.
In early days I sync'ed 2 U-matic players to playout 2 video's. Later I
sync'ed 2 DVD players. My question is ; can I play-out 2 fullscreen QT movies
from 1 Mac over the build-in videocard via the 2 DVI ports and how to
sync this? What scripting or programm can I do? When not what alternative
solution is there? Thank You.

Use cmd + F to set the first video to one screen, then shift +cmd+F to play the second movie full screen on the other monitor.

Some more details; this two movies have to run in an art installation.
They start in the morning frame accurat and stay in sync all day.
It are two loops of the same lenght (3 min.). My question is how to
make a automatic system of this?

You'r best bet is still going to be two DVD players or, if you have the budget, a video server with the capability of playing two streams.
