Looking for an inexpensive way to playback multiple videos in frame accurate sync. I would like it to be scalable to add additional screens\hardware. I know that the Alcorn Mcbride Binloop will do this but it's way out of my price range. The only solution that I have not tried are Brightsign Players that claim to only drift in the milliseconds. I know about Watchout but that to is too expensive. The videos may be up to an hour in length. Any suggestions or help is appreciated.
