This is one piece of equipment that has been a god send and is a must if you do a lot of pieces to camera. We use an Apple MacBook Pro to deliver the script but a word of warning Apple change specs constantly as new flavors of laptops appear but to my horror the latest 15″ unibody version does not have a video adapter so the only way to get a composite picture out of the new MacBook Pro is to use the mini display port to VGA adapter and convert this using an AVerMedia AVerKey Lite (£29) to go from VGA to composite video.
