thanks for your reply.
I wasn't sure if one graphics card would have sufficient processing power to render video etc for four wuxga screens - hence using the four seperate PCs.
Currently i've got the trial download installed on a couple of laptops to check things out - both i7s with 4gb ram, linked by a crossover cable @ 1gb. One's a Geforce 260M, the other a 330M - not amazing cards i know, but not _that_ old either. I've tried sending Big Buck Bunny from one to the other using:
laptop 1: movie in top -> resolution top -> touch out top.
laptop 2: touch in top -> out top
and whenever i set the resolution higher than 800*600 the output gets really jerky. When i was running to an older receiving PC even 800*600 didn't work so great.
As such, i'm slightly concerned about trying to send a possible four movies, each at higher resolution than the Big Buck Bunny to one computer.
I guess i'm doing something really wrong somewhere along the lines, but no idea what it is
I figured it was probably better to send timecode info and then play videos locally, but i've not got that far yet and wasn't sure how well it'd work when a video crosses from one screen to the next.
I'm also trying to work out how to make audio out chops talk to a 32 channel audio card, but that's another story...
