Greetings from Venezuela.
Where I work we sometimes have to play back synchronized videos on several screens (things like fonts jumping from screen to screen and the like), but we're having troubles keeping the different videos synchronized.
What we usually do is to have several DVDs of the same model together, and use one single control to play back, but anytime they loop seems they're a few frames apart, so after a few repeats we have to start them again (using the "back" key on the control) to make them sync up again. Of course that is annoying since it requires someone to do it manually from time to time.
We're basically looking for a way to do that (we've done up to 4 videos but there is something in the horizon that might make us need and keep them synced without having someone to look after it. Maybe a software that could be used on networked PCs to make it play videos at the same time (each one locally stored in one computer) or something like that... any ideas would be welcome.
