You need to replace the video card with a "screen scraper" card; there are a number of these available. The point is that the video signal, once turned analog, has no reverse process to get it back; so instead of doing that, you really want to take the contents of screen memory directly. As I said, there are a number of vendors who sell EGA/VGA cards with no monitor output at all, that you can read the video RAM out of them directly. -- Terry
