As a follow up to this thread
http://forums.creativecow.net/readpost/54/859662, can anyone offer some tips as to how to use a regular teleprompter for this purpose? Basically, we need to know how to feed a composite video signal (from DirecTV) into a laptop and back out the laptop's VGA port to the teleprompter's VGA port. We also need to know how to get that image reversed so the interviewee sees it properly (the teleprompter software usually does that, but we'll need some other method since a video signal can't go through the prompter software).
We were planning to get an EyeDirect 16x9 (http://www.vfgadgets.com/EyeDirect-16x9_p_133.html), but it just uses mirrors to reflect an image of the camera operator back to the interviewee ... we need something that can display a video source to the interviewee directly in front of the camera lens.
