Thanks for your answers.
Matteo : i'm afraid it's the playback which is unsatisfying by itself ..... i' ll have to "upgrade" to better computers.
Thanks also for pointing out this synchro matter, which will be necessary anyway because the videos can last as long as 15 mn.. It should be fine, hopefully, by sending a "master clock" ascending value through udp. Otherwise, if it's like hiccup, i'll keep your idea of comparing incoming values to skip / pause the needed frames.

Marco : which type of macs did you use ? Mine are fairly tired : it's both ibooks, with a 933Mhz processor.

I first tried to launch my videos using VLC with the system object, which was much lighter for the computers. But the sync is not reliable at all, and the windows blink when opening : not clean enough for my installations ...

Yep, I can confirm the same. I worked with three macs connected via LAN and a simple sync via a master works very well.
Also, maybe someone could disagree, but in my experience not-compressed movies (even full DV) are lighter for the machine.

I have synced several computers on a LAN successfully using a master,
with a counter run by a [metro], sending frame numbers to the slaves via
[netsend] and [netreceive], sending the frame number to each [pix_film]
object.

This way the master can also play audio which remains in sync, and
pausing, scrubbing etc are all possible.
