I'd like to write a live video plugin.  I know Mach has one, but I've tried three capture cards and can't get it to work.  I can write the app in VB no problem, but I'm not sure what it takes to make it a plugin.  Ideally, I'd like to have a small video window embedded into the run screen.  It would replace the tool path display window.  If that's not possible, just being to use it like the existing video window would be fine.  Is there a guide to writing plugins?  I'm not even sure where to start.

Thanks for any assistance...
