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.
