If you have any sort of recorder running on the PC then both audio and video via normal routes is at risk. I think the best approach is to drive the monitor directly (as previously suggested (Trevor Jones)) and flash one word at a time (if they are in the same location on screen most people will be able to pick up many words a second). They can't take a picture of it (many words would be missed - digital cameras are slow to respond and film cameras multi shot speed is limited). I've tried using a screen capture program to capture pictures from DVD but they came out blank - this mechanism should have the same effect. The only way to record this is by external video recorder/movie camera. There may be a way of minimising this risk, for example by choosing low contrast or dark colours, very small text etc.
Hmmm, good point.
Most DVD players (and several other applications besides) use video overlays where possible. Of course this requires a video card that supports them, but that's fairly common these days.
The cool thing about overlays is that they're not present in the display's frame buffer at all. They're mixed in on top of the frame buffer sometime shortly before the video card squirts the image out to the RAMDAC. This means that all you get from a screen capture is a blank section in some funky color where the overlay is.
Oh, and you aren't restricted to just playing movies in overlay space. WinAMP's visualisation stuff has an option for using overlays, and they're dynamically generated. Should be simpler to display a static text, right?
Unfortunately, I have no idea how to go about implementing them.
