I know this is probably a total green question, but we are doing a show where we need to play a video as part of the performance. The current option is to hook a DVD player up to the projector (which is on the DS edge of the stage) and have someone backstage with LOS using the DVD player's remote. I mentioned to our production manager that with an upgrade I could play the cues from my macbook, and he was interested. Other than the pro video license, what hardware would I need? I can run the interface via USB, firewire, or Mini DVI. The signal then needs to run about 50 feet to the projector. I know this partially depends on the inputs available on the projector, but it is a very high end projector that we are renting from the local Opera house, so I'm not too worried about that.
